ABSTRACT:
A process for the production of block copolymers of ethylene and an .alpha.-olefin such as propylene by using an ionic catalyst system including a metallocene component and a component having a cation capable of donating a proton and a compatible non-coordinating anion. Novel block copolymers are produced.
