A composition comprising a polyolefin polymer and a core-shell acrylic polymer comprising a high molecular weight processing aid and a carrier resin is disclosed. The high molecular weight processing aid is present in an amount ranging from 30 wt% to less than 100 wt% relative to the total weight of the high molecular weight processing aid and the carrier resin, and the carrier resin is present in an amount ranging from greater than 0 wt% to 70 wt% relative to the total weight of the high molecular weight processing aid and the carrier resin. The composition is in the form of particles having an average particle size of at least 2 mm. 公开了一种组合物，其包含聚烯烃聚合物以及包含高分子量加工助剂和载体树脂的核-壳丙烯酸类聚合物。相对于所述高分子量加工助剂和所述载体树脂的总重量，所述高分子量加工助剂以30重量％至小于100重量％范围的量存在，并且相对于所述高分子量加工助剂和所述载体树脂的总重量，所述载体树脂以大于0重量％至70重量％范围的量存在。所述组合物是平均粒度为至少2mm的颗粒形式。
