Abstract
Well-defined amphiphilic block copolymers of poly(vinyl alcohol)-b-polystyrene (PVA-b-PS) were successfully synthesized by atom transfer radical polymerization (ATRP) of styrene using trichloromethyl (–CCl3) end grouped polyvinyl acetate as macroinitiators which were prepared via telomerization of vinyl acetate with carbon tetrachloride (CCl4) as a telogen, followed by complete hydrolysis of polyvinyl acetate block. The block copolymers were characterized by GPC, FT-IR and 1H NMR. PVA-b-PS has amphiphilic properties, which was confirmed with the study on the surface activity in N,N′-dimethylformamide and toluene. And the Pearlescent pigment which was modified by PVA-b-PS shows improved dispersing stability.
