|Introduction to Macromolecular Chemistry
|Basic definitions, types of polyreactions, constitution of homo- and copolymers, networks, configurative and conformative aspects, contour length, coil formation, mobility, glass temperature, rubber elasticity, molecular weight distribution, energetics of and examples for polyreactions.
|Understanding the significance of molecular size, constitution, configuration and conformation of synthetic and natural macromolecules for their specific physical and chemical properties.
|This introductory course on macromolecular chemistry discusses definitions, introduces types of polyreactions, and compares chain and step-growth polymerizations. It also treats the constitution of polymers, homo- and copolymers, networks, configuration and conformation of polymers. Topics of interest are contour length, coil formation, the mobility in polymers, glass temperature, rubber elasticity, molecular weight distribution, energetics of polyreactions, and examples for polyreactions (polyadditions, polycondensations, polymerizations). Selected polymerization mechanisms and procedures are discussed whenever appropriate throughout the course. Some methods of molecular weight determination are introduced.
|Course materials (consisting of personal notes and distributed paper copies) are sufficient for exam preparation.
