催化剂和共聚单体的选择提高了二氧化碳气固相反应的选择性，使甲基丙烯酸缩水甘油酯（GMA）的氧环烷部分转化为环碳酸酯部分。苄基三丁基氯化铵（BnBu3NCl）由于在共聚物膜中具有适当的迁移率和中等的催化活性而表现出良好的选择性催化行为。正甲基丙烯酸丁酯被证明是一种有效的共聚单体，通过防止交联反应，可以获得更高的掺入效率和更好的选择性，从而获得具有环状碳酸盐结构的可溶性聚合物。
The appropriate choice of catalysts and comonomers improved the selectivity of the gas−solid-phase reaction of carbon dioxide into copolymers from glycidyl methacrylate (GMA), which transforms the pendent oxirane moieties to cyclic carbonate moieties. Benzyltributylammonium chloride (BnBu3NCl) exhibited good and selective catalytic behavior owing to its appropriate mobility in the copolymer film and moderate catalytic activity. n-Butyl methacrylate proved to be an effective comonomer, resulting in higher incorporation efficiency and better selectivity by preventing the cross-linking reaction, allowing one to obtain soluble polymers bearing cyclic carbonate structure.
