Outline syllabus

This is an indicative module outline only to give an indication of the sort of topics that may be covered. Actual sessions held may differ.

Here follows an illustrative syllabus for each section of the module.
Part 1. Polymers (16 lectures + 4 workshops)
BLOCK 1: Polymer Physics
LECTURE 1: Introduction to the fascinating material features of polymers in the liquid state. Polymer solutions and polymer melts. Introduce the concept of viscosity (and visco-elasticity: the latter by means of a movie to watch as homework).
LECTURE 2: Understand the conformation of a polymer chain in the liquid state. The concepts of end-to-end distance, radius of gyration. A recap of molar mass distributions and the introduction of size exclusion chromatography.
LECTURE 3: Understand the structure of polymers in the solid state. Amorphous and crystalline states. The solid-liquid phase transition. The concept of a glass transition, the concept of crystalline polymers. Note that elastomers/gels/rubbers will only be addressed briefly.
LECTURE 4: Concepts and details of Tg, crystallinity, XRay (SAXS and WAXS), DSC, DMA
WORKSHOP 1
BLOCK 2: Step-growth/Condensation Polymerization
LECTURE 5: The underlying chemistry: polyesters, polyamides and polyaramids, polyurethanes, polycarbonates, etc.
LECTURE 6: Conducting polymers and polymers for OPV applications
LECTURE 7: Polymers from renewable sources, problems associated with replacing oil based chemistry, use of carbon dioxide
LECTURE 8: Hyperbranched polymers, dendrimers and gels
WORKSHOP 2
BLOCK 3: Chain-growth/Addition Polymers I
LECTURE 9: The concept of chain-growth/addition polymerization. Free radical, or ionic. Number degree of polymerization. Molar mass distributions in chain-growth polymerizations. The concept of tacticity, NMR.
LECTURE 10: The mechanism of free radical polymerization: initiation (radical generation and first monomer addition), propagation, bimolecular termination, and chain-transfer. Kinetic chain-length. Mayo-Equation
LECTURE 11: Case study: A closer look at a commercially important addition polymer.
LECTURE 12: Free radical copolymerisation
WORKSHOP 3
BLOCK 4: Living Polymerization
LECTURE 13: The concept of living polymerization: control of chain-growth. Its effect on the molar mass distribution and ability to control monomer sequence. Living ionic polymerization.
LECTURE 14: Living ionic ring opening polymerization of ethylene oxide, caprolactone, caprolactam. Group transfer polymerization
LECTURE 15: Case study: a closer look at a commercially important polymer made via living polymerization.
LECTURE 16: Biodegradable polymers for ring opening polymerisation and from fermentation including polymers from lactides, glycolides, etc
