摘要
The invention relates to polymethacrylate ester/polysiloxane block copolymer of the ABA or AB type, A being a polymethacrylate ester block and B a polysiloxane block. The invention furthermore relates to a method for the synthesis of such block copolymers as well as to a method to modify synthetic resins, particularly those based on (meth)acrylates, by adding an effective amount of the inventive block copolymer. The invention also relates to the block copolymer as additives for organic lacquer and varnish systems.
