A series of fluorine-containing polyacrylic epoxy (FPAE) prepolymers with different fluorine content and molecular weight are synthesized by solution free radical polymerization of hexafluorobutyl methacrylate (HFBMA), butyl acrylate (BA), and glycidyl methacrylate (GMA). The synthesized prepolymers show high conversion and low volume shrinkage. The effect of different types of active diluent for the cationic UV curing of FPAE was investigated, among which oxetane exhibits better comprehensive property than epoxy and vinyl ether. The formulations with the optimal ratio of different functionality oxetane combination show good flexibility, adhesion, hydrophobicity, and antistain property.

氧杂环丁烷作为活性稀释剂对含氟环氧预聚物阳离子UV固化体系的影响

通过甲基丙烯酸六氟丁酯(HFBMA)、丙烯酸丁酯(BA)和甲基丙烯酸缩水甘油酯(GMA)的溶液自由基聚合合成了一系列不同氟含量和分子量的含氟聚丙烯酸环氧(FPAE)预聚物。合成的预聚物显示出高转化率和低体积收缩率。研究了不同类型活性稀释剂对FPAE阳离子UV固化的影响,其中氧杂环丁烷比环氧和乙烯基醚表现出更好的综合性能。具有最佳配比的不同官能度氧杂环丁烷组合的配方表现出良好的柔韧性、粘附性、疏水性和抗污性。
