ABSTRACT:
Blends of polyetherimides and block poly(esteramides) may contain about 99-1% by weight of the former and about 1-99% of the latter. Particularly useful are polyetherimides containing about 1-30% of the block poly(esteramide), which have improved impact strength and resistance to brittleness. The blends may also contain at least one poly(alkylene dicarboxylate) as a compatibility improver.
