【Abstract】 With DMF as solvent,the kinetics of copolymerization systems of four N p \|substituted phenyl maleimides with styrene in solution was systematically studied by means of dilatometry.The polymerization rate equation of N phenyl maleimide with styrene is R \-p= k \ 1/2 [M].The polymerization rate of other N p \|substituted phenyl maleimides with styrene were also a linear function of monomer concentration.The overall apparent copolymerization rate constants and apparent copolymerization activity energy of the four N p \|substituted phenyl maleimides with styrene were determined,which confirmed that the polymerization activity of the four N p \|substituted phenyl maleimides with styrene decreases in an order as follows: N p \|chlorophenyl maleimide, N phenyl maleimide, N p \|tolylphenyl maleimide and N p \|tolyloxyphenyl maleimide.The apparent copolymerization activity energy of N p \|chlorophenyl maleimide with styrene was the smallest because the polarization difference between N p \|chlorophenyl maleimide and styrene was the biggest.The result was in accordence with the theory of CTC complex,which provided the evidence of the existence of CTC complex.更多还原
