Moulding composition based on polypropylene

摘要

Moulding materials (I) comprise (A) polymers of propylene and≤20 wt.% other monomers, contg. (B) 0.05-0.4 wt.% mono- or poly-basic carboxylic acid amide(s) with a mol. wt. of 150-600 and (C) 0.1-3.0 wt.% ethylene polymer with≤20 wt.% comonomers, with a density of 0.890-0.945 g/cm<3> and a MFI 190/2.16 of 10-100 g/10 mins.. Also claimed are films and mouldings made from (I), such as injection syringes. Pref. (A) is a polypropylene homopolymer or a copolymer of 90-99.9 wt.% propylene and 0.1-10 wt.% ethylene and/or 4-10C alk-1-ene. (B) is 13-docosenoic acid amide (erucamide) and/or 9-octadecenoic acid amide (oleamide), in amts. of 0.08-0.2 wt.%.
