.alpha.-olefins and olefin polymers and processes therefor

Abstract From the Canadian patent

Disclosed heroin arc processes for polymerizing ethylene acyclic olefins, and/or selected cyclic olefins and optionally selected olefinic, eaters a carboxylic acids and other monomers. The polymerizations are catalysed by selected transition metal compounds and sometimes, other co-catalysts. Since some of the polymerizations exhibit some characteristics of living polymerizations block copolymers can be, readily made. Many of the polymers produced are often novel particularly in , regard to their microstructure which gives some of them, unusual properties. Numerous novel catalysts are disclosed as well as some , novel processes for making them. The polymers made are useful as elastomers, …
