ABSTRACT:
A process for the copolymerization of alpha-olefins to form a block olefinic copolymer. In these processes solid polymeric alpha-olefin which contains an active catalyst is fed into two parallel fluid-bed reactors and concurrently, two different, gaseous, olefinic monomer streams are cyclically fed into first one reactor and then the other. The block olefinic copolymer is continuously withdrawn from the reactors during the cyclic injection thereinto.
