摘要

The copolymerization of 2-hydroxyethyl acrylate (HEA

M1) and methylmethacrylate (MMA

M2) in cyclohexanone was studied. The multiple experiments ofsolution copolymerization with low conversion were carried out at two sensitive compositionfeed points at 60

100

120 and 140℃

respectively. The composition of the copolymerswas analyzed by 1H-NMR. The reactivity ratios which were estimated by the Error-in-Variable Method (EVM) of Mayo-Lewis equation were found to be r1 = 0.328

r2 = 1.781for 60℃; 0.375

1.709 for 80℃;0.406

1.654 for 100℃;0.439

1.540 for 120℃ and 0.455

1.400 for 140℃

and the 95% joint confidence intervals of the reactivity ratios were also determined.According to r1 and r2

Arrhenius relations and the activity energy difference between the homo- and cross-propagation were calculated.
