The invention relates to the field of petrochemical industry, and discloses a composition with the function of initiating polymerization and a method for preparing an acrylamide copolymer. The composition with the function of initiating polymerization contains organic amine and at least one compound represented by formula I, and the weight ratio of the two is 1:0.0001-10000. In addition, the invention also discloses a method for preparing an acrylamide copolymer, comprising: polymerizing a monomer mixture in water in the presence of an initiator provided by the composition of the invention. By using benzophenone compounds as initiators, higher polymerization efficiency (acrylamide copolymer with higher viscosity-average molecular weight) can be obtained at lower initiation temperature. |
