Abstract
Polymer blends with improved impact strength consisting essentially of a polyamide and a copolymer of an .alpha.-olefine, an amide and an ester of an .alpha.,.beta.unsaturated carboxylic acid.
Claims9
Polymer blends with improved impact strength consisting of:
- (I) from 70 to 99% by weight of at least one polyamide and
- (II) from 1 to 30% by weight of a high molecular weight olefinic copolymer having a melting point of at least 100.degree. C. and a melt index of from 1-20 g/10 min. at 190.degree. C. measured according to DIN 53 735 consisting of:
- (a) from 65 to 98% by weight of at least one .alpha.-olefine,
- (b) from 1 to 15% by weight of at least one amide of an .alpha.-.beta.-unsaturated carboxylic acid and
- (c) from 1 to 20% by weight of at least one alkyl or alkenyl ester of an .alpha.,.beta.-unsaturated carboxylic acid, the sum of (I) and (II) and the sum of (a)-(c) being in each case always 100% by weight.
