Abstract: Disclosed is a composition comprising a polyolefin polymer and a core-shell acrylic polymer comprising a high molecular weight processing aid and a carrier resin. The high molecular weight processing aid is present in an amount ranging from 30% to less than 100% by weight 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% to 70% by weight 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.
