Abstract

The invention concerns a method and an equipment for taking a sample in slurry polymerization. The sample is taken directly from the liquid phase of the reactor (15) through an in-line filter (40). The slurry flow is maintained in the in-line filter (40) at a sufficiently hight level to prevent immobilization of polymer or catalyst particles on the filter face of the in-line filte (40).
