Abstract: In a block copolymer (I) containing at least two hard blocks (S1, S2) prepared from a vinylaromatic monomer (M1) and, between them, at least one soft block (BS) prepared from M1 and a diene (M2), the proportion of hard blocks is over 40 wt.% of total (I). Independent claims are also included for the following: (a) mixtures of (I) and additional styrene polymers; and (b) preparation of (I) by sequential anionic polymerization, with at least polymerization of BS being in presence of a potassium salt.

Abstract: The invention relates to thermoplastic molding material containing the constituents A) to F), 5 to 80 wt. % of a graft polymer A) with a bimodal particle size distribution, 20 to 95 wt. % of a thermoplastic polymer B) with a viscosity VZ of 50 to 120 ml/g and optionally other thermoplastic polymers C), D) and/or E) based on at least one vinyl-aromatic monomer, and optionally additives F). The inventive material can be obtained by 1) producing the graft polymers A) according to the emulsion polymerization method, 2) mixing the graft polymer A) with polymer B) and, insofar as they are available, the other constituents C), D), E) and/or F) in a mixing device, whereby a substantially molten polymer mixture arises and 3) rapidly cooling the substantially molten polymer mixture.

Abstract: Production of rubber-modified styrene polymers (I) comprises (1) producing rubber (II) dispersion by anionic dispersion polymerization of diene and optionally styrene monomer(s) in 3-6 carbon aliphatic hydrocarbon (III) which is nonsolvent for (II); (2) mixing intensively with styrene monomer and optionally comonomer, without separating (III), to dissolve (II) in monomer(s); and (3) anionic or free radical polymerization of (II) solution to (I) and simultaneous removal of (III). An independent claim is also included for rubber-modified styrene polymers made by this process.
