Use of polyamide moulding compounds in processes for injection moulding objects of high impact strength.

摘要

The invention relates to a process for injection moulding objects having a high impact strength from a moulding compound and said moulding compound of polyamide 6 and/or 66 in which there is dispersed 1-50% by weight of a segmented polyether-polyamide copolymer prepared by polycondensation of alpha , omega -poly (propylene oxide) diamine having a molecular weight in the range of 400 to 4000 and a substantially equimolar amount of dicarboxylic acid, and polyamide forming monomers, at least 50% by weight of which consists of caprolactam, and in which the polyether segments form 10-80% by weight of the copolymer, and in which compound there is blended 0,001-5% by weight of a lubricant suitable for use in the injection moulding of polyamide.
