Abstract: The invention relates to a method for producing particulate polymers P by radically initiated aqueous emulsion polymerization, wherein at least one ethylenically unsaturated monomer is emulsified by means of a dispersing agent in an aqueous medium and polymerized by means of a radical polymerization initiator in the presence of a stable N-oxyl radical so that an aqueous polymer dispersion is obtained. According to the inventive method: a) a peroxide, a hydroperoxide and/or an azoic compound are used as a radical polymerization initiator, whose molar solubility at 25 DEG C and 1 bar in water is greater than or the same as the corresponding molar solubility of tert-butyl hydroperoxide in water and whose decomposition temperature in a polymerization medium is

The concentration of at least one cross-linking agent varies in the hard segment. A process for producing these segments is also disclosed, as well as graft copolymers which contain these segments, a process for producing these graft copolymers and thermoplastic compounds containing these graft copolymers, moulded bodies, foils, fibres and coatings which contain at least one of the disclosed segments, graft copolymers and thermoplastic compounds.

Abstract: In a process for producing modified rubber moulding materials, 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, a compound (b) having the general formula (II), in which R stands for a hydrogen atom or a methyl group, R stands for a hydrogen atom or an alkyl group with 1 to 8 carbon atoms, R stands for a hydrogen atom or a methyl group and R stands for a hydrogen atom, an alkyl group with 1 to 10 carbon atoms, preferably hydrogen, and optionally a first or several other monomers (c), is polymerised together with free radicals into a rubber (B). In a second step, the thus obtained rubber (B) is mixed with a second or several other monomers (d), preferably dissolved or swollen therein, to form a second mixture (C). In a third step, the second mixture (C) is polymerised together with free radicals into the modified rubber moulding material (D).
