    Abstract: Expandable styrene polymers (I) for elastic polystyrene (PS) foam contain: (a) 75-99 wt.% PS and/or styrene copolymer contg. at least 50 wt.% styrene; (b) 0-24 wt.% styrene-soluble elastomer(s); (c) 1-25 wt.% core-shell type graft copolymer(s); (d) 1-15 wt.% (w.r.t. a+b+c) low-boiling blowing agent(s), and opt. (e) conventional additives. Also claimed are processes for the prodn. of (I) (see below). Also claimed is elastic PS foam contg. (a), (b), (c) and (e) in amts. as above. Also claimed is a process for the prodn. of PS foam by heating (I) at a temp. above the softening pt. so as to expand the particles and weld them together in a non-gastight mould. Pref. component (b) is polybutadiene, polyisobutylene or ethylene-propylene rubber, pref. polybutadiene. (c) is a core-shell graft copolymer, pref. with a core of a polymer with a Tg of 20 to -60 degrees C and a shell of harder material, in amts. of 40-80 wt.% and 20-60 wt.% respectively. Pref., the core consists of a copolymer of 40-90 wt.% alkyl (meth)acrylate and 10-60 wt.% styrene, and the shell of a copolymer of 80-99 wt.% styrene and 1-20 wt.% alkyl (meth)acrylate.

    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.

    Abstract: Compsns. (I) comprise mixt. of (A) 20-80wt.%, on A+B, first thermoplastic resin (II) contg. units of (a1) 60-90wt.%, on A, at least one 8-12C vinylaromatic hydrocarbon; (a2) 40-10wt.%, on A, acrylonitrile, Me methacrylate, and/or N-phenylmaleimide; (B) 80-20wt.%, on A+B, second thermoplastic resin (III) contg. mixt. of (b1) 50-90wt.% reactive terpolymer of (b1a) 60-90wt.% at least one 8-12C vinylaromatic hydrocarbon; (b1b) 15-35wt.% acrylonitrile, Me methacrylate, and/or N-phenylmaleimide; (b1c) 1-20wt.% maleic-acid or -anhydride, glycidyl methacrylate, and/or vinyloxazoline; (b2) 50-10wt.% elastomer with reactive gps. from maleic-acid or -anhydride, glycidyl methacrylate, and/or vinyloxazoline, polymerised in (b2a) linear or branched copolymer of Tg below 0 deg.C, or graft-polymerised on (b2b) elastomer based on butadiene homopolymer, copolymer of butadiene with up to 30wt.% comonomer, (co)polymer of acrylate ester from 2-8C alcohol, or ethylene-propylene(-diene copolymer rubber).
