Abstract: Thermoplastic molding masses based on the copolymerization of styrene and/or alpha -methylstyrene and acrylonitrile, which may be modified to be impact resistant with rubberlike polymers, are made antistatic by adding 0.01 to 1.5 percent by weight of a graft polyol which is a polyhydroxy-polyalkylene polyether modified with styrene-acrylonitrile copolymers.

Abstract: Thermoplastic moulding materials comprises (A) 1-70 wt.% (w.r.t. A+B) of a graft copolymer comprising an elastomer a1 and a shell a2 grafted onto the elastomer, the elastomer a1 consisting of butadiene alone or a copolymer of butadiene with up to 30 wt.% on a1 of styrene or acrylonitrile and having an ave. particle size of 100-750 micrometres (d50-value of the integral wt. distribution), and making up 90-50 wt.% of (A), and the shell a2 being made up of at least one 8-12C vinyl aromatic monomer (a22) and at least one monoethylenically unsatd. monomer (a23), and making up 10-50 wt.% of (A); and (B) 99-30 wt.% (w.r.t. A+B) of a copolymer hard matrix comprising (b1) at least one 8-12C vinylaromatic monomer and (b2) at least one mono-ethylenically unsatd. monomer. The grafted shell a2 is made in two stages in which (1) in a first stage, 5-50 wt.% w.r.t. a2) exclusively of the vinyl aromatic monomer is graft polymerised and (2) in a second stage 50-95 wt.% (w.r.t. a2) of a mixt. of a22 and the monomer a23 in a wt. ratio of 90:10 to 66:34 is graft polymerised in the presence of the elastomer a1.

Abstract: Reinforced thermoplastic moulding compsn. consists of (A) 40-94 (wt.) copolymer of (a1) 90-50% styrene (IA), alpha-methylstyrene (IB) and/or a ring alkyl-substd. styrene deriv. (IC) and (a2) 10-50% (meth)acrylonitrile (IIA) and/or methyl (meth)acrylate (IIB), (B) 20-0.5% terpolymer of (B1) 90-50% (I), (b2) 5-40% (II) and (b3) 2-30% of another monomer (III) and (C) 5-50% reinforcement (IV). The novelty is that (III) is t-butyl (meth)acrylate. The compsn. may also contain, w.r.t. A + B + C, (D) 1-50% graft copolymer(s) of (d1) 50-90% tubber(s) with Tg below 0 deg.C, (d2) 10-49% vinyl-aromatic monomer(s) with max. 12C atoms and (d3) 49-1% (IIA) and/or 1-8C-alkyl (meth)acrylate(s); and/or (E) up to 20% usual additives. The pref. compsn. is (A) 50-87% copolymer of 80-60% (I) and 20-40% (II), (B) 10-0.5% terpolymer of 90-50% (I), 5-40% (II) and 5-15% (III) and (C) 15-40% (IV); partic. (A) 55-65% copolymer of 80-20% (IA) and 20-40% acrylontrile (IIA-1), (B) 10-0.5% terpolymer of 85-60% (IA), (IIA-1) and 5-15% (III) and (C) 20-40% glass fibres.
