Abstract
Impact modifier polymer powders are isolated by a process comprising introducing about 0.5 to 50% by weight of stearate coated calcium carbonate having an average particle size of about 0.04 to 1 micron based on polymer and stearate coated calcium carbonate mixture. The resultant mixture has improved anti-compaction properties as well as powder flow. Blends of impact modifier and thermoplastic matrix polymer are also unexpectedly improved. Impact modifier with higher than normal rubber levels can be isolated.
