    摘要: An elastomeric acrylate copolymer which contains, as polymerized units, comonomers having chemically reactive groups is prepared for the preparation of molding materials having good weathering resistance, improved impact strength and good flow properties. This copolymer is dissolved or swollen in monomers such as styrene and acrylonitrile, forming hard graft shells. After the addition of monomers and/or polymers having chemically reactive groups and, if required, after the addition of a chemically reactive crosslinking agent, the resulting monomer/copolymer mixture is subjected to graft polymerization, which is carried out up to a conversion of more than 15% by weight of the monomers, by thermal or free radical mass or solution polymerization. The molding materials can be used as dulling agents for polymer blends.
