Abstract: The invention relates to rubber-modified, high-impact moulding compositions containing, based on the sum of A, B1 and B2, A: from 70 to 98% by weight of a polymer matrix A, formed by free radical-initiated polymerisation of a mixture of from 60 to 90% by weight of styrene and from 10 to 40% by weight of acrylonitrile, and B1: from 1 to 29% by weight of a particulate, first graft polymer B1 distributed in the matrix and comprising a graft base of polybutadien and graft branches of a copolymer of styrene and acrylonitrile, having a mean particle size of from about 100 to 500 nm, B2: from 1 to 29% by weight of a particulate, second graft copolymer B2 distributed in the matrix and comprising a graft base of polybutadien and graft branches of a copolymer of styrene and acrylonitrile having a mean particle size of from 600 to 10000 nm, as obtained by preparing the two graft copolymers in solution and/or bulk and incorporating them into the polymer matrix in a conventional manner. e

Abstract: A process for the continuous preparation of high-impact polystyrene-acrylonitrile (ABS) by the free radical-initiated polymerisation of a mixture of from 60 to 90% by weight of at least one vinyl aromatic monomer and from 10 to 40% by weight of at least one further ethylenically unsaturated monomer in the presence of from 5 to 30% by weight, based on the sum of the monomers, of polybutadiene having a solution viscosity (5% strength by weight in styrene at 25 DEG C) of from 25 to 95 mPa.s and optionally in a solvent, in at least three series-connected reactors operating essentially with no back-mixing, at reaction temperatures of from 50 to 170 DEG C, phase inversion occurring in one of the reactors, the polymerisation being carried out as far as phase inversion at a temperature of 90 DEG C or below and being initiated by free radicals formed from the decomposition of tert.-butyl peresters whose half life period at 90 DEG C is not more than 20 minutes, the polybutadiene content, based on the total reaction mixture, being at least 10% by weight, and at most 25% of the entire amount of chain-transfer agent (regulator) required being added before phase inversion and the remainder thereafter.

Abstract: Rubber-modified, impact-resistant ABS moulding materials (I) are claimed. (I) are obtd. by polymerisation of styrene (S) and acrylonitrile (AN) in a soln. of preformed rubber in (S), (AN) and opt. a solvent; the novelty is that (I) contains, as rubber, a styrene-butadiene (SB) block copolymer and other polymer(s) (II) which is/are compatible with the polystyrene component of the rubber and Also claimed is a process for the prodn. of (I), by radical polymerisation of (S) and (AN) by known methods in a reaction mixt. contg. (S), (AN), initiator, opt. a solvent, SB block copolymer rubber and (II). Pref., in addn. to the SB rubber, (I) also contains a polybutadiene rubber; (II) is polystyrene, poly(cyclohexyl) (meth)acrylate) and/or PPE. USE/ADVANTAGE - The addn. of (II) in combination with the SB rubber gives ABS (I) (esp. injection moulding materials) with a combination of high surface gloss and high notch impact resistance, which can be produced by soln. or bulk polymerisation.
