Abstract

Olefins containing selected functional groups such as silyl, ether and alkenyl, and often containing a blocking group, may be copolymerized with unsubstituted olefins such as ethylene and propylene in the presence of certain coordination compounds of nickel or palladium. The resulting polymers are useful as molding resins, elastomers, in adhesives and for films.
