Abstract (en)

[origin: WO0183574A1] The invention relates to a graft copolymer comprising a1: 10 to 90 wt.- % of a particulate graft base A1 from a particulate emulsion polymer having a glass transition temperature of below 0 DEG C produced from a11: 70 to 100 wt.- % butadiene or at least one C1-8 alkyl ester of acrylic acid or mixtures thereof as the component A11, a12: 0 to 20 wt.- % of at least one polyfunctional cross-linking monomer as the component A12, a13: 0 to 30 wt.- % of further copolymerizable monomers as the component A13, totaling 100 wt.- %, a2: 10 to 90 wt.- % of a graft layer A2 from the monomers, based on A2, a21: 60 to 100 wt.- % of at least one vinyl aromatic monomer, one (meth)acrylic acid ester or mixtures thereof, as the component A21, and a22: 0 to 40 wt.- % of at least one ethylenically unsaturated monomer as the component A22. The inventive graft polymer has an average particle size of from 130 to 500 nm and a polymodal particle size distribution in which in every particle size interval having a width of 50 nm less than 40 wt.- % of the particles are present.
