AMPHIPHILIC BLOCK COPOLYMER USABLE AS A SURFACTANT WITH EXCELLENT SELF-ASSEMBLY, EMULSIFYING PERFORMANCE, MOISTURIZING, AND MOISTURE ABSORPTION, A MANUFACTURING METHOD THEREOF, AND A COSMETIC COMPOSITION INCLUDING THEREOF

摘要

PURPOSE: A manufacturing method of an amphiphilic block copolymer is provided to simplify synthesis of a RAFT polymerization method which can accurately control molecular weight without a metallic catalyst, and to obtain uniform size distribution.;CONSTITUTION: An amphiphilic block copolymer comprises polyester as a hydrophobic block, and polyphosphoryl choline as a hydrophilic block. A manufacturing method of the amphiphilic block copolymer comprises: a step of polymerizing a polyester block through ring-opening polymerization; a step of adding a chain-moving reactant into the polyester block; and a step of adding phosphoryl choline into the polyester block, and polymerizing a polyester-polyphosphoryl chlorine block copolymer by a living radical method.;COPYRIGHT KIPO 2013
