Novel Polymeric Surfadditives Synthesized via Atom Transfer Radical Polymerization and Their Surface Migration Properties

Abstract Multi‐functional tri‐block copolymers having fluorinated and triethoxysilane side chains and polyacrylate backbone have been synthesized and used as surface‐active additives (termed as “surfadditive”) in molding and casting acrylic parts. The fluorinated block facilitates migration of surfadditive molecules to the part surface and the acrylate block provides rooting to the part matrix, while the silane block offers functionality to the …
