CHEM 773/7730-01 - Polymer Properties and Polymerization

Semester: Winter 2021

Professor: J. Duhamel | Discipline: Polymer |

Description

  1. Refresher on basic concepts: Homopolymers vs. copolymers, molecular weight distributions and averages, polydispersity, free radical addition polymerization.
  2. Emulsion polymerization: Initiators, surfactants and other components. Polymerization rate and molecular weight control.
  3. Copolymerization equation, monomer reactivity ratios. Types of behaviors: random, alternating, blocky copolymers. Integrated copolymerization equation. Copolymer microstructure. Multicomponent polymerization. Structural effects, Q-e scheme, kinetics.
  4. Anionic polymerization: initiation, propagation, termination. “Living” polymerizations. Solvent and temperature effects, reactivity modifiers, stereochemistry control. Cationic polymerization: initiation, propagation, chain transfer, temperature effects.
  5. Coordination polymerization: Ziegler-Natta catalysts, supported catalysts, stereochemistry control.
  6. Polymer mixtures. Solution thermodynamics, solubility parameter and variations, Flory-Huggins theory. Applications of solution thermodynamics: plasticization, fractionation, polymer mixtures (blends).
  7. Polymer self-associations: Close/open association mechanism, supramolecular polymerization.
