Thermoplastic moulding materials - contain modified polyphenylene ether, polyolefin, vinyl]-aromatic-diene] block copolymer and opt. fibrous and/or particulate filler

摘要

Thermoplastic moulding materials (I) contain mainly (A) 10-89 wt.% modified polyphenylene ether, (B) 10-89 wt.% polyolefin, (C) 1-40 wt.% block copolymer of a vinylaromatic cpd. and a conjugated diene, and (D) 0-60 wt.% fibrous and/or particulate filler. Amts. are 15-80 wt.% (A), 15-80 wt.% (B) and 5-35 wt.% (C), or 15-79 wt.% (A), 15-79 wt.% (B), 1-20 wt.% (C) and 5-30 wt.% (D); (B) is polypropylene and/or ethylene-propylene copolymer; (C) is partly or fully hydrogenated styrene-butadiene (SB) block copolymer; (D) is glass and/or carbon fibre. USE/ADVANTAGE - (I) are useful for the prodn. of moulded prods. (claimed); moulded prods. obtd. from (I) are also claimed as such. The invention provides (I) with good impact resistance, satisfactory rigidity and low water absorption, suitable esp. for the prodn. of bodywork parts and functional parts for motor vehicles and moulded prods. for the electrical industry.
