Catalysis in Polymer SynthesisExamines the role of catalysis in applied polymer developments, focusing on metal catalysis of olefins, epoxides, oxetanes, cyclic phosphazenes, and cyclic silanes. Provides discussion of metal catalyzed coordination polymerization of olefins and diolefins and ring opening coordination polymerization of epoxides and oxetanes. Covers recent developments on anionic and cationic polymerization. Places particular emphasis on early and recent developments on propylene polymerization as related to isotactic and syndiotactic propylene. Provides a review of the work of E.J. Vandenberg, recipient of the 1991 ACS Award in Applied Polymer Science, in olefin, epoxide, and oxetane polymerization. |
