BULK FLOWABLE IMPACT MODIFIER PARTICLES, PROCESSES FOR MAKING THEM AND COMPOSITIONS CONTAINING THEM

摘要

Compositions useful as impact modifiers for hard polymers comprise particles of multi-stage impact modifier, having at least one hard and at least one elastomeric stage, coated and/or agglomerated with hard polymer which does not contain an elastomeric stage. These compositions have better bulk flow properties than the multi-stage impact modifier particles alone. Weight ratios of hard polymer to impact modifier are 0.1 to 99.9 to 10:90.
