Process for preparation of olefin polymers comprising extraction of gaseous samples for analysis

A process for preparing an olefin polymer in a polymerization apparatus in the presence of a solid particulate polymerization catalyst and an organometallic compound, comprising: withdrawing a gaseous stream from the polymerization apparatus, passing the gaseous stream through a bed of particulate solids having chemical groups reactive with the organometallic compound on the surface, and feeding the sample of the gaseous stream into an analyzer. 一种用于在固体颗粒聚合催化剂和有机金属化合物存在的情况下在聚合设备中制备烯烃聚合物的工艺，包括：从聚合设备中抽取气态料流，使气态料流穿过在表面具有与有机金属化合物具反应性的化学基团的颗粒固体床，以及将气态料流的样品进料到分析仪中。
