摘要
通过自由基聚合反应制备得到了羟基丙烯酸酯树脂,探讨了聚合时间、聚合温度、引发剂、反应溶剂等影响因素对分子质量、分子质量分布和固含量的影响。通过优化合成条件,制备得到了超低分子质量的羟基丙烯酸酯树脂,其数均相对分子质量小于4 000,分子质量分布≤3.0,高固低黏特征显著。
A kind of hydroxyl acrylate resin is synthesized by free radical polymerization. The effects of polymerization time, temperature, types of initiators, solvents on the molecular weight,PDI and solid content are studied. The hydroxyl acrylate resin with lower molecular weight (Mn ≤4 000, PDI ≤3.0) can be obtained under the optimal reaction condition, which has obviously low viscosity and high solid content.
