【Abstract】 The polymerization of MA, MMA and VC have been carried out by catalyst Al(iBu)3/H2O, AlEt3/H2O and AlEt2Cl/H2O. The effect of polymerization conditions on the polymerization of MA has been investigated. The higher polymer yield and polymerization conversion can be obtained when the H20/Al(iBu)3 ratio is about 1 to 2. According to the results of UV and other experiments, the active species can be formed by complexlng MA, Al(iBu)3 and water.更多还原
