COPOLYMERS BASED ON METHACRYLATE UNITS, PREPARATION METHOD THEREOF AND USE OF SAME

摘要

The invention relates to a method for preparing a copolymer having a backbone based on methacrylate units, comprising a step involving the polymerisation of one or more precursor methacrylate monomers of said units in the presence of: a polymerisation initiator, at least one RAFT-type transfer agent which can generate a primary radical, and at least one comonomer selected from among styrene monomers and acrylate monomers. The invention also relates to the resulting copolymers, in particular block copolymers, and to the use thereof as additives for plastic materials.
