Harmful by inhalation, in contact with skin and if swallowed. Irritating to eyes, respiratory system and skin. Highly flammable. POTENTIAL HEALTH EFFECTS ACUTE HEALTH EFFECTS SWALLOWED ! Accidental ingestion of the material may be harmful; animal experiments indicate that ingestion of less than 150 gram may be fatal or may produce serious damage to the health of the individual. EYE ! Irritation of the eyes may produce a heavy secretion of tears (lachrymation). ! The vapour when concentrated has pronounced eye irritation effects and this gives some warning of high vapour concentrations. If eye irritation occurs seek to reduce exposure with available control measures, or evacuate area. ! There is evidence that material may produce eye irritation in some persons and produce eye damage 24 hours or more after instillation. Severe inflammation may be expected with pain. SKIN ! Skin contact with the material may be harmful; systemic effects may resultfollowing absorption. ! The material may cause moderate inflammation of the skin either following direct contact or after a delay of some time. Repeated exposure can cause contact dermatitis which is characterized by redness, swelling and blistering. ! Minor exposure to methyl acrylate may cause sensitisation in some cases In a vase study involving 105 exposed workers 53. 7 % showed the clinical presence of three allergies (dermatitis, eczema, urticaria). ! Open cuts, abraded or irritated skin should not be exposed to this material. ! Entry into the blood-stream, through, for example, cuts, abrasions or lesions, may produce systemic injury with harmful effects. Examine the skin prior to the use of the material and ensure that any external damage is suitably protected. INHALED ! Inhalation of vapors or aerosols (mists, fumes), generated by the material during the course of normal handling, may be harmful. ! The material can cause respiratory irritation in some persons. The body's response to such irritation can cause further lung damage. ! Inhalation of quantities of liquid mist may be extremely hazardous, even lethal due to spasm, extreme irritation of larynx and bronchi, chemical pneumonitis and pulmonary edema. ! If exposure to highly concentrated vapor atmosphere is prolonged this may lead to narcosis, unconsciousness, even coma and unless resuscitated - death. ! There is some evidence to suggest that this material can cause, if inhaled once, irreversible damage of organs. ! The use of a quantity of material in an unventilated or confined space may result in increased exposure and an irritating atmosphere developing. Before starting consider control of exposure by mechanical ventilation. CHRONIC HEALTH EFFECTS ! Long-term exposure to respiratory irritants may result in disease of the airways involving difficult breathing and related systemic problems. Inhaling this product is more likely to cause a sensitization reaction in some persons compared to the general population. Skin contact with the material is more likely to cause a sensitization reaction in some persons compared to the general population. There has been some concern that this material can cause cancer or mutations but there is not enough data to make an assessment. Limited evidence suggests that repeated or long-term occupational exposure may produce cumulative health effects involving organs or biochemical systems. In a 13-week study of methyl acrylate, rats were given up to 20 mg/kg/day in drinking water. Treatment related effects were seen in rats receiving higher doses and included spontaneous renal disease. The no-observed-effect level (NOEL) was 5 mg/kg/day. In an inhalation study rats, rabbits and guinea pigs were exposed to methyl methacrylate 7 hours/day. All animals exposed at 578 ppm (two-seven times) died. These animals exhibited ocular and respiratory tract irritation, salivation, laboured breathing, lethargy and/or convulsions. Signs of toxicity at 237 ppm were similar to those at 578 ppm. Rats exposed to methyl methacrylate vapour for up to 2 years showed concentration-related changes in the transitional region between the respiratory and olfactory nasal epithelium ranging from very mild to mild atrophy of ciliated and olfactory cells. No animals showed signs of squamous cell metaplasia at concentrations up to 135 ppm. Corneal opacification and vascularisation occurred at all concentrations. Severity was dependent on concentration and duration. 2 of 13 Section 3 - COMPOSITION / INFORMATION ON INGREDIENTS NAME CAS RN % methyl acrylate 96-33-3 >98 inhibitor stabiliser, must be present for transport and storage; more inhibitor means longer storage life typically 4-methoxyphenol (MEHQ) 150-76-5 0.001-0.1 Section 4 - FIRST AID MEASURES SWALLOWED · IF SWALLOWED, REFER FOR MEDICAL ATTENTION, WHERE POSSIBLE, WITHOUT DELAY. · Where Medical attention is not immediately available or where the patient is more than 15 minutes from a hospital or unless instructed otherwise: EYE ! If this product comes in contact with the eyes: · Wash out immediately with fresh running water. · Ensure complete irrigation of the eye by keeping eyelids apart and away from eye and moving the eyelids by occasionally lifting the upper and lower lids. SKIN ! If skin contact occurs: · Immediately remove all contaminated clothing, including footwear · Flush skin and hair with running water (and soap if available).

New L-serine derivative ligands were prepared and tested as cocatalyst in the Diels-Alder reactions between cyclopentadiene (CPD) and methyl acrylate, in the presence of several Lewis acids. The catalytic potential of the in situ formed complexes was evaluated based on the reaction yield. Bidentate serine ligands showed good ability to coordinate medium strength Lewis acids, thus boosting their catalytic activity. The synthesis of the L-serine ligands proved to be highly efficient and straightforward. 1. Introduction derivative ligands, as alternative to the usual strong Lewis acids.

O’Reilly * Well-defined N,N’-(dimethylamino)ethyl acrylate (DMAEA) functionalized polymeric stars have been syn- thesized via an arm-first approach. Utilizing reversible addition–fragmentation chain transfer polymeriz- ation, linear homopolymers (PEGA, PHEA) were chain extended with DMAEA and a divinyl crosslinker to produce a series of crosslinked polymeric stars. These stars were characterized using a range of tech- niques including NMR, SEC, DLS and TEM analysis. The hydrolytic behavior of the DMAEA when tethered within a micellar core was investigated by 1H NMR spectroscopy and was found to be strongly dependent on temperature. At elevated temperatures either a higher crosslinking density or a longer arm length was found to offer greater protection to the amine resulting in slower hydrolysis, with hydrolysis found to level off at a lower final percentage hydrolysis. In contrast, the composition and nature of the arm was found to Creative Commons Attribution 3.0 Unported Licence. have little impact on the hydrolysis, with the same trends relating to the effect of temperature and cross- Received 7th February 2017, linking density observed with a linear (HEA) and a brush (PEGA) arm.
