    • A process includes contacting a metallic acrylic salt with a polyolefin, forming a polyolefin composition. The process includes extruding the polyolefin composition, and pelletizing the extruded polyolefin composition. A production rate of pellets of the polyolefin composition may be equal to or greater than a production rate of pellets of the polyolefin prior to contact with the metallic acrylic salt without increasing extrusion pressure or motor amperes. The polyolefin composition may have a melt flow rate that is lower than the melt flow rate of the polyolefin prior to contact with the metallic acrylic salt. The metallic acrylic salt may only be contacted with the polyolefin to form the polyolefin composition during a start-up of an extruder and pelletizer.
    • 一种方法包括使金属丙烯酸盐与聚烯烃接触,形成聚烯烃组合物。 该方法包括挤出聚烯烃组合物,并将挤出的聚烯烃组合物造粒。 聚烯烃组合物粒料的生产速率可以等于或大于聚烯烃粒料在与金属丙烯酸盐接触之前的生产速率,而不增加挤出压力或马达安培。 该聚烯烃组合物的熔体流动速率可以低于与金属丙烯酸盐接触之前的聚烯烃的熔体流动速率。 金属丙烯酸盐只能在挤出机和造粒机启动期间与聚烯烃接触以形成聚烯烃组合物。
