Abstract

Polymerization of olefins in a reactor system having two reactors in series, more particularly a process for the polymerization of monomer in at least first and second reactors operated in series. The process includes contacting a first stream containing vapor derived from the effluent withdrawn from the second reactor with a feed stream to the second reactor, the feed stream containing effluent derived from the first reactor.
