| titleOfInvention | Multistage graft copolymer and its use for the preparation of transparent pvc molding materials |
| abstract | Graft copolymers obtained by A) emulsion polymerization of from 5 to 35% by weight of a monomer mixture of a1) 60-80% by weight of one or more vinylaromatic monomers, a2) 20-40% by weight of one or more ethylenically unsaturated nitriles, B) subsequent emulsion polymerization, in the presence of the emulsion polymer obtained in stage A), of 20-45% by weight of a monomer mixture of b1) 50-75% by weight of one or more vinylaromatic monomers, b2) 25-50% by weight of one or more C1-C18-alkyl acrylates, C) subsequent emulsion polymerization, in the presence of the emulsion polymer obtained in stage B), of 5-35% by weight of a monomer mixture of c1) 60-80% by weight of one or more vinylaromatic monomers, c2) 20-40% by weight of one or more ethylenically unsaturated nitriles, D) subsequent emulsion polymerization, in the presence of the emulsion polymer obtained in stage C), of 15-45% by weight of a monomer mixture of d1) 80-99.9% by weight of one or more C1-C18-alkyl acrylates, d2) 0.1-0% by weight of one or more di- or polyethylenically unsaturated monomers. The graft copolymers can be used for the preparation of transparent PVC molding materials. |
