Summary

The characteristics of step polymerization are discussed, with emphasis on the parameters that control polymer molecular weight. The rate and molecular weight in both reversible and irreversible polymerizations are discussed together with the process conditions needed for producing different polymers. Monomer conversion and stoichiometry determine the polymerization rate and polymer molecular weight. The conditions needed to achieve crosslinked, hyperbranched, dendrimer, block, and other polymer architectures are described. Specialty polymers are considered, including high-temperature, conducting, polyrotoxanes, inorganic, and organometallic polymers. The synthesis and uses of thermoplastic and thermoset materials. Polyamides, polyesters, polycarbonates, phenolics, epoxy resins, polyurethane, polysiloxanes, polyimides, and other commercial polymers are discussed.
