A process for preparing styrenic resins is disclosed which comprises the steps of:a) adding monomer material selected from the group consisting of monomers and monomer mixtures being capable of forming a rubbery polymer by polymerization and preferably comprising an acrylic acid ester to a polymericb) contacting the polymeric matrix and the monomer material under conditions in which said monomer is absorbed by said polymeric matrix; andc) polymerizing said monomer material with formation of a rubbery polymer partly grafted on the polymeric matrix. The resulting styrenic resin exhibits good impact strength and gloss. |
