McGrath, James E. – Journal of Chemical Education, 1981
The salient features and importance of chain-reaction polymerization are discussed, including such topics as the thermodynamics of polymerization, free-radical polymerization kinetics, radical polymerization processes, copolymers, and free-radical chain, anionic, cationic, coordination, and ring-opening polymerizations. (JN)

Stille, J. K. – Journal of Chemical Education, 1981
Following a comparison of chain-growth and step-growth polymerization, focuses on the latter process by describing requirements for high molecular weight, step-growth polymerization kinetics, synthesis and molecular weight distribution of some linear step-growth polymers, and three-dimensional network step-growth polymers. (JN)

Ward, Thomas Carl – Journal of Chemical Education, 1981
Focuses on molecular weight and molecular weight distributions (MWD) and models for predicting MWD in a pedagogical way. In addition, instrumental methods used to characterize MWD are reviewed with emphasis on physical chemistry of each, including end-group determination, osmometry, light scattering, solution viscosity, fractionation, and…

Mattice, Wayne L. – Journal of Chemical Education, 1981
Suggests the topic of macromolecules and synthetic polymers be included in undergraduate courses. Two macromolecular systems (polyethylene in a state unperturbated by long-range interactions and a polypeptide undergoing a helix-coil transition) are described which are suitable for inclusion in the statistical mechanics section of physical…

Bazuin, C. G.; Eisenberg, A. – Journal of Chemical Education, 1981
Demonstrates how the incorporation of relatively low amounts of ionic material into nonionic polymers affects the structure and properties of these polymers. The extent to which properties are altered depends on dielectric constant of the backbone, position and type of ionic group, counterion type, ion concentration, and degree of neutralization.…
