| Abstract: | Acrylonitrile (AN) and ammonium salt of itaconic acid (NH4)2IA] were polymerized in aqueous deposited polymerization systems to synthesize high molecular weight AN/(NH4)2IA copolymers, which were initiated by ammonium persulphate (NH4)2S2O8] . Effects of initiator concentration, monomer concentration, monomer ratio, polymerization temperature and polymerization time on copolymerizations were investigated. It is found that the reaction rate of the aqueous deposited copolymerization is faster and the copolymers obtained have higher viscosity average molecular weight (MV) up to (38 ~ 75)×104. |
