    Abstract: Production of aqueous polymer dispersions by radical initiated aqueous emulsion polymerisation of ethylenically unsaturated monomer(s) (I) comprises emulsifying (a) a mixture of (I) with radical initiator(s) and stable N-oxyl radical(s) or (b) a mixture of (I) with compound(s) which decompose on heating to give stable N-oxyl radicals and polymerisation initiating radical partners, with the aid of dispersants to give an aqueous emulsion with a disperse phase mainly comprising droplets with a diameter \} 500 nm, and then polymerising the emulsion at elevated temperature. Also claimed are the aqueous polymer dispersions.

    Abstract: A hard segment H1 is disclosed with a glass transition temperature of at least 10 DEG C which contains at least one polymerised vinyl aromatic monomer as monomer or one among two or several monomers that can be copolymerised together, at least one cross-linking agent with two or more functional groups of different reactivities and at least one cross-linking agent with two or more functional groups of the same reactivity. 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.
