A NOVEL FREE-RADICAL INTERFACIAL COPOLYMERIZATION

Free radical interfacial copolymerization which is carried out by mean s of an amphiphilic bifunctional initiator as a novel polymerization m ethod was proposed for the first time. For utilizing the new polymeriz ation method, an amphiphilic bifunctional initiator, palmitoyl (3-carb oxy propionyl) sebacoyl diperoxide (PSD), was synthesized and further used to initiate the free radical interfacial copolymerization of acry lamide (AM) with n-butyl methacrylate (n-BMA) which gave the amphiphil ic PAM/PnBMA block copolymers. The resulting PAM/PnBMA block copolymer s were purified by solvent extraction and characterized by elemental a nalysis, solubility, IR and DSC.
