Abstract
Diethylene glycol monoallyl ether (DGME) was synthesized by reaction of diethylene glycol with allyl chloride. Then, a novel non-ionic functional polyurethane surfactant (PUS) was synthesized by the polycondensation of hexamethylene diisocyanate (HMDI) with polypropylene glycol (PPG-1000) and DGME. Next, a series of polyvinyl acetate (PVAc), polybutyl acrylate (PBA), and polystyrene (PSt) latexes have been successfully synthesized, each one throughout by the emulsion copolymerization in the presence of a PUS. This polymeric surfactant exhibited excellent surface activity, and the surface tension decreased with an increase in the concentration of the polyurethane surfactant. [ABSTRACT FROM PUBLISHER]
