Abstract
The invention relates to impact-resistant injection mouldings based on polyamide resin (A) and on a disperse phase whose particles have a number-average diameter greater than 0.4 .mu.m, a volume-average diameter greater than 1 .mu.m and such that more than 50% by volume of the particles are larger than 1 .mu.m The disperse phase may consist of a mixture including at least one copolymer (B) of ethylene and of an unsaturated epoxide and of at least one polyolefin (C).
Claims11
An impact-resistant injection moulding, comprising polyamide resin (A) and a disperse phase whose particles have a number-average diameter greater than 0.4 .mu.m, a volume-average diameter greater than 1 .mu.m wherein the disperse phase consists of a mixture including at least one copolymer (B) of ethylene and of an unsaturated epoxide and of at least one polyolefin (C), wherein the quantity of epoxide in the copolymer (B) is up to 10% and the proportions of (B) and (C) are such that (C)/(B) is from 95/5 to 80/20.
