摘要

Abstract

The photopolymerization of acrylamide (AAm) was studied by using N-methacrylyl-N'-pyrimidinopip (MPMP) as sensitizer under UV irradiation.The photopolymerition rate of AAm in water with MPMP as sensitizer is proportional to 0.36th power of MPMP comcentration and 0.88th power of AAm concentration. The overall activation energy for the polymerization is determined to be 5.02Kcal/mol. A super-high MW (107) of PAAm are obtained. The MW is decreased with both the increasing of MPMP concentration and the raising of polymerizat-ion temperature

and inereased with the increase of AAm concentration. Fluoresce-nt analysis indicates that MPMP not only initiates the photopolymerization of vinyl monomers

but also enters into the polymer chains.
