The present invention relates to an amorphous polyolefinic ionomer and a process for the preparation of an amorphous polyolefinic ionomer.

The present invention relates to an amorphous polyolefinic ionomer and a process for the preparation of an amorphous polyolefinic ionomer.

This invention relates to a process to produce an ionomer comprising: 1) contacting, in a reactor, one or more C.sub.2-C.sub.60 α-olefins, an optional diene, and a metal alkenyl with a catalyst system comprising an activator, a catalyst compound, and a support; 2) forming a copolymer comprising one or more C.sub.2-C.sub.60 α-olefin monomers and about 0.01 wt % to about 20 wt %, based on the weight of the copolymer, of metal alkenyl; 3) functionalizing and quenching the polymerization reaction with one or more electrophilic groups; and 4) obtaining ionomer.
