Abstract: A process for the slurry polymerization of one or more α-olefins in a sequence of at least two loop reactors interconnected by means of a transfer line, the transfer of polymer from a first loop reactor to a second loop reactor comprising the steps: i) establishing a recycle of polymer slurry to the second loop reactor by means of said transfer line, whereby a fraction of polymer slurry S1 withdrawn from said second loop reactor is continuously recycled back to it; ii) discharging a fraction of polymer slurry produced in the first loop reactor into a discharge line connected to said transfer line;

Abstract translation: 一种用于通过传输线互连的至少两个环管反应器的序列中的一种或多种α-烯烃的淤浆聚合的方法，聚合物从第一回路反应器转移到第二回路反应器，包括步骤：i） 通过所述传输管线建立聚合物浆料到第二回路反应器的再循环，由此从所述第二回路反应器排出的聚合物浆料S1的一部分被连续循环回到其中; ii）将在第一回路反应器中产生的聚合物淤浆的一部分排放到与所述输送管线相连的排出管线中;
