Toughened blends of alpha polyamides and functionalized block copolymers
摘要:
This invention is a toughened alpha-polyamide composition which has been admixed at a maximum shear rate of at least 400 sec−1 and which comprises: (a) 10 to 30, preferably 15 to 25, percent by weight (%wt) of a maleic anyhydride or acid functionalized polydiene polymer, (b) 60 to 89% wt of an alpha-polyamide, and (c) 1 to 10% wt of a polyamide prepared by copolymerizing a diamine and a dicarboxylic acid.
