摘要
为制备气干型不饱和聚酯 ,在三氟化硼乙醚溶液存在下 ,对失水甘油烯丙醚进行开环聚合 ,制成了具有一定聚合度的失水甘油烯丙醚预聚体 ,探索了聚合反应的最佳条件 ,使预聚体的产率达到 98% ,测定了预聚体的粘度、分子量、聚合度、环氧值、不饱和度 (碘值 )等参数 。
For the sake of preparation the air drying unsaturated polymerester, the pre polymer with certain polymerization degree of glycidyl allyl ether was polymerized by opening ring of glycidyl in the precence of the catalyst of BF 3ether. Optimum reaction conditions were studied. The yield of pre polymer was up to 98%. The product structurally was characterized by IR. The viscosity, molecular weight, polymerization degree, epoxy value and unsaturated value of the title compound were determined.
