Abstract: An elastomeric particulate polymer is prepared using ethylenically unsaturated monomers in the presence of a radical initiator has a small particle size and is readily precipitated from a dispersion. The elastomeric particulate polymer (I) is prepared by: (a) dispersing (A11) 85-100 wt.% ethylenically unsaturated monomers, whose homopolymer is elastomeric and (A12) 0-15 wt.% of a crosslinking monomer in water in the presence of a protective colloid and an emulsifier to form a dispersion having an average particle diameter of 0.08-8 micro m; (b) polymerization of the droplets with a radical polymerization initiator; and optionally (c) graft polymerization of the resulting mixture in the presence of ethylenically unsaturated monomers. Independent claims are included for: (i) a molding composition comprising 0.1-80 wt.% of (A); 20-99.9 wt.% of a polymer matrix (B); 0-50 wt.% of a fibrous or particulate filler (C); and 0-30 wt.% of further additives (D). (ii) fiber, film or molded articles prepared from the molding composition.

Abstract: In a process for producing modified rubber moulding masses, a first mixture (A) that contains at least one alkyl acrylate or methacrylate (a) having the general formula (I), in which R stands for a hydrogen atom or a methyl group and R stands for an alkyl group with 1 to 32 carbon atoms, at least one first monomer (b) that forms radicals by thermal decomposition, and optionally a second or several other monomers (c), is in a first step polymerised into a rubber (B), preferably together with free radicals. In a second step, the thus obtained rubber (B) is mixed with a third or several other monomers (d), preferably dissolved or dipped therein, to form a second mixture (C), and in a third step the second mixture (C) is polymerised with free radicals into the modified rubber moulding mass (D).

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.
