Abstract
In a process for producing elastomers of ethylene and C.sub.3 to C.sub.10 alpha-olefins, improved products, higher catalyst efficiency, improved monomer conversion and control of molecular weight distribution are obtained by the use of staged reactors wherein the monomer feed is divided between the reactors, the catalyst feed is added to the first reactor and the cocatalyst feed is divided with a different cocatalyst supplied to the second reactor. The process is applicable in either a divided single reactor or in the use of multiple reactors.
