数均分子量小于3000、等二元结构的液体聚丁二烯,用有机酸与过氧化氢作环氧化剂,氯仿作溶剂,在室温下可得到不同环氧氧含量的环氧化聚丁二烯。在相同的反应条件下,用甲酸比用乙酸时的反应速度快。可采用不加硫酸催化剂、减少有机酸用量、选择适当的反应温度和相应地控制反应时间等方法,以避免或减少环氧基的羟基化开环副反应。 Number average molecular weight of less than 3000, and other binary structure of liquid polybutadiene, organic acids and hydrogen peroxide as epoxidizing agent, chloroform as a solvent at room temperature can be epoxidized polybutadiene with different epoxy oxygen content . In the same reaction conditions, with formic acid than with acetic acid when the reaction speed. Can be used without sulfuric acid catalyst to reduce the amount of organic acids, select the appropriate reaction temperature and the corresponding control of the reaction time and other methods to avoid or reduce the hydroxyl group of epoxy ring-opening side reactions.
