摘要： Processes for producing blends of a first polymer component and a second polymer component are provided. The first polymer component and the second polymer component are blended in an internally agitated mixer such as a devolatizer in the presence of at least one solvent. Blending the polymers in this manner results in an intimate mixing of the first and second polymers, providing beneficial performance characteristics. In one embodiment, the first polymer incorporates at least 75 wt. % of propylene-derived units wherein the propylene-derived units have an isotactic triad fraction of about 65% to about 99% and wherein the first polymer has a heat of fusion of less than 75 J/g. In this embodiment, the second polymer is selected from polypropylenes, low density polyethylenes, high density polyethylenes, polystyrenes, polyamides, polycarbonates, and polyesters. Pellets of such polymer blends exhibit beneficial elasticity properties of the first polymer component while exhibiting a reduced tendency to agglomerate.
