Flory Assessment: 1000 points CHE 355 and CH 367L Comprehension Evaluations 80% (800 points) Attendance at a discussion hour 20% (200 points) CHE 392P and CH 392N Comprehension Evaluations 80% (800 points) Paper, topic presentation 20% (200 points) Comprehension Evaluations: These are assignments to accompany recorded lecture material. You may use the lectures, books, articles, and lecture notes to complete these assignments. They are not timed or proctored and are handed in approximately once every other week on Sunday night by the latest by upload to canvas. Paper or topic presentation: Graduate students will be asked to deliver a short presentation (ca. 10 minutes) to the class during the Wednesday synchronous sessions. The topics will be on current research, ChE 355/ChE 392P/CH 367L/CH 392N Page 1 of 9 or a classic paper that resulted in course content. These sessions will be recorded and questions will appear on the comprehension evaluation based on their presentations. Discussion hour: This is a one hour session where several of you will meet with me in a small group zoom meeting. Topics for discussion might include current developments in polymer chemistry, career development, coursework, etc. You must participate in one discussion hour. While I will attempt to hold the discussion hour at a fixed time that is available to everyone in the class, it is likely that the time will be moved during the semester. Exam Dates: No exams. Final Exam Policy: No final exam. Re-Grading: Re-grade requests may be submitted in writing (e-mail) up to one week after the item was graded. Grading: +/– grading will be used. A standard scale is anticipated. A > 94% A– > 90% B+ > 87% B > 84% B– > 80% C+ > 77% C > 74% C– > 70% Absences: No excuses for missed tests, exams, or quizzes will be accepted other than written certified medical excuses or written letters on university letterhead for UT-related school activities. By UT Austin policy, you must notify me of your pending absence at least fourteen days prior to the date of observance of a religious holy day. If you must miss a class, an examination, a work assignment, or a project in order to observe a religious holy day, you will be given an opportunity to complete the missed work within a reasonable time after the absence. COURSE EXPECTATIONS Knowledge, abilities and skills students should have entering this course: 1. A general understanding of synthetic organic chemistry. 2. A basic understanding of thermodynamic concepts such as free energy, enthalpy, and entropy. 3. Some math skills consistent with a technical background. Knowledge, abilities and skills students should gain from this course: This course has two main objectives. The first is to introduce synthetic aspects of polymer science, while also presenting many of the polymers that society uses today. The second objective is to introduce the polymer physics underlying polymer properties. By the end of this course, students should be able to: 1. Become familiar with the terminology, conventions, names, and many polymers used by society today. ChE 355/ChE 392P/CH 367L/CH 392N Page 2 of 9 2. Understand the spectrum of methods used to make polymers and their scope, relative strengths, and weaknesses, and the effect of reactivity on polymer architecture, composition, and stereochemistry. The polymer chemistry portion of this course will cover the following: o Distinguishing features of polymers over small molecules o Step-growth polymerization § Kinetic and thermodynamic considerations § Examples o Chain growth polymerization § Controlled polymerization (fast initiation, no termination, no equilibrium) § Controlled polymerization (fast initiation, no termination, equilibrium) § Controlled polymerization (slow initiation, no termination, no equilibrium) § Uncontrolled polymerization (continuous initiation and termination) § Copolymerization • Non-terminal (ideal) model • Terminal model, and more complicated models • Description of stereochemical control of polymerization o Isoselectivity versus o Enantioselectivity § Examples 3. Understand the core concepts that form the basis for many of the physical properties of polymers. The polymer physics portion of this course will cover the following: o Polymer conformation: § Description of polymer spatial extent § Statistical models for chain statistics § Shortcomings of current models o Thermodynamics of polymer solutions: § Regular solution theory § Flory-Huggins theory § Osmotic pressure (osmometry) § Phase behavior of polymer solutions (bimodal,spinodal,critical point)’ § Interactions o Light scattering by polymer solutions § Basic concepts of light scattering (light, X-ray, neutron, etc.) § Scattering by an isolated molecule § Scattering from a dilute polymer solution § Form factor and the Zimm equation § Scattering regimes and particular form factors o Dynamics of dilute polymer solutions o Networks, gels, and rubber elasticity o Linear viscoelasticity o Glass transition o Crystallinity o Mechanical properties 4. Current topics in polymer science, e.e., o Reinforced composites (e.g., carbon fiber) o Block polymer self-assembly SUGGESTED COURSE SCHEDULE ChE 355/ChE 392P/CH 367L/CH 392N Page 3 of 9 **This syllabus represents my current plans and objectives. As we go through the semester, those plans may need to change to enhance learning opportunities. Such changes are not unusual and will be communicated clearly.
