Abstract:The copolymerization of 4\|vinyl pyridine(4\|VP) with acrylamide(AM) has been realized by radical copolymerixation in solution using potassium persulfate as initiator.The effects of acetone/water and DMF/water solvent systems,comonomer concentration,polymerization temperature,polymerization time and initiator amount on the conversion of the polymerization and molecular weight were investigated in detail.The results showed that the mixed solvent DMF/water=1( V/V) is suitable for the copolymerization of 4\|VP and AM.The composition of copolymer was determined by ultraviolet spectrophotometry and the structure of copolymer was characterized and verified by FTIR and 13 C\|NMR.Finally,The monomer reactivity ratios of 4\|VP and AM were obtained with Kelen\|Tudos method, r \- 4\|VP =0\^644, r AM =0 371.
Keywords:Acrylamide  4\|Vinyl pyridine  Solution copolymerization  Reactivity ratio
