The process is particularly applicable to the effluent from a slurry polymerization reactor which has been GC used to produce a polypropylene homopolymer or copolymer having a first molecular weight and at least part of the effluent is to be 1-1 © supplied to a slurry polymerization reactor to produce a polypropylene homopolymer or copolymer having a second, higher molecular f'1 weight.
