研究了甲基丙烯酸缩水甘油酯-甲基丙烯酸二乙酯共聚物环氧基团在不同浓度硫酸溶液中的水解。水解的近似活化能为41 kJ mol−1，由温度依赖性确定。为了进行比较，在整个pH值范围内考察了pH对水解度的影响，并讨论了结果相对于所用共聚物的其他反应的重要性。
Hydrolysis of the epoxide groups of the copolymer glycidylmethacrylate - ethylenedi-methacrylate in variously concentrated sulphuric acid solutions was studied. An approximate activation energy of hydrolysis, 41 kJ mol−1, was determined from the temperature dependences. For the sake of comparison the effect of pH on the degree of hydrolysis over the whole range of pH values was examined, and the importance of the results with respect to other reactions of the copolymer used was discussed.
