  • Recent Advances in Cationic Photopolymerization
    Journal of Photopolymer Science and Technology Volume 32, Number 2 (2019) 233 － 236 Ⓒ 2019SPST Recent Advances in Cationic Photopolymerization Marco Sangermano Politecnico di Torino, Dipartimento di Scienza Applicata e Tecnologia, C.so Duca degli Abruzzi 24, 10129, Torino, Italy [email protected] The paper reports important strategies to overcome limitation of cationic photopolymerization. First, it was possible to run emulsion cationic photopolymerization in water, taking the advantages of hydrophobic droplets of suitable dimension to avoid termination reaction, achieving capsules of about 200 nm. Subsequently a frontal polymerization reaction is used to promote the UV-induced crosslinking process of an epoxy composites via a radical induced cationic frontal polymerization.

Introduction the main limitation of UV-induced crosslinking Cationic photopolymerization is an interesting reactions is related to the hindering of UV-light UV-induced process since the mechanism is penetration towards thickness of the formulations, characterized by important advantages such as which limits this polymerization technique in the absence of oxygen inhibition, low shrinkage upon preparation of thick composite materials.

  • Epoxy Resin-Photopolymer Composites for Volume Holography
    Chem. Mater. 2000, 12, 1431-1438 1431 Epoxy Resin-Photopolymer Composites for Volume Holography Timothy J. Trentler, Joel E. Boyd, and Vicki L. Colvin* Department of Chemistry, Rice University, Houston, Texas 77005 Received December 28, 1999. Revised Manuscript Received February 23, 2000 Efficient materials for recording volume holograms are described that could potentially find application in archival data storage. These materials are prepared by mixing photopo- lymerizable vinyl monomers with a liquid epoxy resin and an amine hardener. A solid matrix is formed in situ as the epoxy cures at room temperature. The unreacted vinyl monomers are subsequently photopolymerized during hologram recording. A key feature of these materials is the separation of the epoxy and vinyl polymerizations. This separation allows for a large index contrast to be developed in holograms when components are optimized. The standard material described in this work consists of a low index matrix (n = 1.46), comprised of diethylenetriamine and 1,4-butanediol diglycidyl ether, and a high index photopolymer mixture (n = 1.60) of N-vinylcarbazole and N-vinyl-2-pyrrolidinone. This material is functional in thick formats (several millimeters), which enables narrow angular bandwidth and high diffraction efficiency. A dynamic range (M/#) up to 13 has been measured in these materials. Holographic performance is highly dependent on the amount of amine hardener used, as well as on photopolymer shrinkage.

The solidification depends on the length of time of exposure to UV light, and the intensity of that light, which reduces with distance from the irradiative surface. Liquid prepolymer was solidi- fied inside the gap of a parallel disk rheometer by irradiation of the prepolymer with UV light through a fixed quartz disk. The rheological time-dependent changes were measured and analyzed for both unidirectional and oscillatory shear. The results were compared with those obtained by direct measurement in the absence of shear. When the thickness of the sample was less than 0.1 mm, the analysis for unidirectional shear flow yielded a rea- sonable agreement for both critical exposure and solidified depth. When the thickness was greater than 0.1 mm, the application of unidirectional shear delayed the start of the solidification but then caused it to occur more rapidly. This dependence of the solidification on the thickness of the sample was more significant for dispersed systems of nanotubes and for dynamic measurements made under oscillatory shear. The increase in viscosity due to photopolymerization was also estimated, and its effect was discussed. Zusammenfassung: Wir beschreiben eine Reihe von rheologischen Messungen, die durchgeführt wurden, um die Verfestigung von Photopolymeren zu charakterisieren.

  • Theprocessfor2pieces (Template)
    This year’s IMDA conference, “Innovation and Technology; Keeping Us Competitive”, made me recognize what others in our two-piece industry feel is lacking; that being some type of standardization - which is critical for the shared understanding of new technologies and processes. I would like to address one facet of this issue by identifying terminology and processes used to make printing plates. Our industry has seen substantial changes over the past five-to-seven years. The terms that I use may not be the same as terms used by the can industry, but they are terms used throughout the printing and graphic arts industry. Analog The analog process has been used since the introduction of photopolymer printing plates. What is photopolymer? Photopolymer is a plastic, light-sensitive material used as a printing plate. To create an image on the plate, a material is required that will let light through in certain areas while blocking light in other areas. A film negative that is black and clear is used for this purpose. The clear area lets light pass through while black areas of the film block the light, preventing exposure to the photopolymer. Areas of the photopolymer plate exposed to light are cross-linked, creating an image on the plate. Unexposed areas of the plate that do not receive light are not cross-linked. What is cross-linking? Photopolymer plates use an ultra-violet (UV) light inhibitor that reacts to a certain wavelength of light. A cross-link is a bond that links one polymer to another after exposure to UV light.

Sheridan1* 1School of Electrical, Electronic and Communications Engineering, College of Engineering and Architecture, Communications and Optoelectronic Research Centre, The SFI-Strategic Research Cluster in Solar Energy Conversion, University College Dublin, Belfield, Dublin 4, Ireland. 2Department of Computer Science, National University of Ireland Maynooth, Maynooth, Co. Kildare, Ireland. *Corresponding author: [email protected]; Tel: +353 (0)1 716 1927 ABSTRACT The Non-local Photo-Polymerization Driven Diffusion (NPDD) model was introduced to describe the observed drop-off in the material’s response for higher exposing spatial frequencies. Recent work carried out on the modeling of the mechanisms which occur in photopolymers during- and post-exposure, has led to the development of a tool, which can be used to predict the behaviour of these materials under a wide range of conditions. In this article, based on the chemical reactions of chain transfer agents, we explore this extended NPDD model, illustrating some of the useful trends, which the model predicts and we analyse their implications on the improvement of photopolymer material performance. Keywords: Holography, photopolymer material, chain transfer agent. 1.

Triggered by the UV light, the duo function group monomer 1,6-Hexamethylene diacrylate (HDDA), photoinitiator 1173 and photoinhibitor exhibit a fast curing process. The exothermal photopolymerization reaction was performed in the isothermal mode in order to evaluate the different thermal effects that occurred during the photopolymerization process. The influences of both UV light intensity and exposure time were studied with single-factor analysis. The results obtained by photo-DSC also allow us to perform the kinetic study of the polymerization process: The results show that, for the reaction, the higher the UV intensity, the higher the curing degree together with faster curing speed. At the same time, the effect of the heat released during the exothermic reaction is negligible for the polymerization process. When increasing the exposure time, limited improvement of curing degree was shown, and the distribution is between 65–75%.
