The effects of reaction medium (alcohol,dioxane,dioxane/alcohol)on the heterogenous polymerization of acrylamide initiated by BDC (benzyl diethyldiothiocarbate)were studied. The results showed that herterogenous polymerization differed from homogeneous solution polymerization initiated by BDC and did not have the character of living radical polymerization. The polarity of reaction medium affected the enolization of acrylamide obviously,and made the yield of polymer and molecular weight different from each other, behaving obvious solvent effects.The UV spectra of products and polymerization of acrylamide initiated by products,show that iniferter functional groups remained in products.
