ABSTRACT:
A polymerization process is carried out in at least two zones, wherein in one zone polymerization is effected in the presence of a liquid phase which is at least one liquid olefine monomer and in a subsequent zone polymerization is effected by contacting the solid polymer with a gaseous olefine monomer, the product from the first zone being subjected to a concentration stage to remove some of the liquid olefine monomer before the concentrated polymer mixture is passed to the subsequent zone for polymerization with the gaseous olefine monomer. The monomer in each case may be the same, for example liquid propylene in one zone and gaseous propylene in a subsequent zone. The concentration stage may be effected using a hydrocyclone.
