| Abstract: | Bulk copolymerization of styrene (St, M 1)with β hydroxy ethyl acrylate (HEA, M 2)were carried out at 60,80.100,120 and 140℃ at two sensitive feed compositions.Compostions of copolymers were analyzed by elemental analysis (EA).The relative reactivity ratios were calculated by Error in Variable method (EVM) to be ( r 1=0 313, r 2=0 224),(0 349,0 225),(0 409,0 291),(0 525,0 327) and (0 565,0 347) at different temperatures.The differences of activation energies,entropies,and ethalpies between homopropagation and cross propagation,were calcutated too. |
