Abstract

Abstract: A polyazoester initiator was used to synthesize polystyrene/polyaerylamide (PSt/PAM) block polymers by its consecutive decomposition in styrene(St) and aerylamide(AM). The polymerization behavior of AM in 1,4-dioxane initiated by an azo group-containing styrene prepolymer (prePSt) was investigated, and the factors influencing the conversion of the second monomer and the content of the homopolystyrene were discussed. The PSt/PAM block polymers were characterized by elemental analysis, solubility, IR, DSC, TG and pyrolysis-gas chromatography.

Key words: amphiphilic polymer, block polymer, polyazoester initiator, polystyrene/polyacrylamide block polymer, synthesis
