摘要：POLYURETHANE (PU) WITH POLY(2-(DIMETHYLAMINO)ETHYL METHACRYLATE) (PDEM) SIDE CHAINS HAS BEEN PREPAR...POLYURETHANE (PU) WITH POLY(2-(DIMETHYLAMINO)ETHYL METHACRYLATE) (PDEM) SIDE CHAINS HAS BEEN PREPARED BY COMBINATION OF RADICAL POLYMERIZATION AND POLYADDITION.SUCH AN AMPHIPHILIC COPOLYMER CAN SELF-EMULSIFY IN WATER AND FORM NANOPARTICLES.THE EFFECTS OF PH AND TEMPERATURE ON PARTICLE STABILITY HAVE BEEN EXAMINED BY PARTICLE AND ZETA POTENTIAL ANALYZER.IT SHOWS THAT THE NANOPARTICLES ARE STABLE IN ACIDIC OR ALKALINE MEDIUM.THE NANOPARTICLES WERE EMPLOYED AS THE SOLE EMULSIFIER FOR EMULSION POLYMERIZATION OF STYRENE (ST).OUR STUDIES DEMONSTRATE THE PU BASED NANOPARTICLES CAN EFFECTIVELY STABILIZE ST DROPLETS AND FORM PU/PS COMPOSITE EMULSIONS IN SITU.显示全部
