KR960022804A - Method for preparing antifouling polymer mixture and antifouling coating composition containing same - Google Patents

Abstract

The present invention relates to a method for preparing an antifouling polymer mixture and an antifouling coating composition containing the same, wherein the antifouling component, hydrophilic component, and hydrolysis component are known in the art to which the present invention belongs, such as ethylene, propylene, styrene, alkyl, and acrylate. It is composed of copolymerizing with one or more monomers of unsaturated monomers to prepare a polymer, to add a methyl ester compound to prepare a polymer mixture, and the antifouling coating composition using this mixture is free from coating defects such as film cracking and peeling. Excellent antifouling purpose can be achieved by synergistic effect by self polishing and varnish itself toxicity.
