摘要：以羟甲基松香和丙三醇为起始化合物与环氧丙烷和环氧乙烷进行嵌段缩聚反应(KOH为催化剂)得到不同羟甲基松香含量和不同环氧链节的松香聚醚多元醇。研究了羟甲基松香、环氧丙烷用量对产物羟值、黏度的影响。采用FT-IR对产物的结构进行了表征,通过TGA分析比较了产物松香聚醚多元醇和其他类型多元醇的热性能。结果表明,松香聚醚多元醇的耐温性一般高于马来松香酯多元醇和工业聚醚4110。松香聚醚多元醇中羟甲基松香的引入对耐热性起到重要作用,其质量分数越高,耐温性越高,当起始物全部为羟甲基松香时,初始分解温度可达376.0℃。
The rosin -based polyether polyols with different hydroxymethyl rosin contents and different epoxy segments were synthesized by block polycondensation reaction of propylene epoxide , ethylene epoxide and starting materials including hydroxymethyl rosin and glycerol in the presence of alkaline catalyst. The effects of hydroxymethyl rosin and propylene epoxide content on the hydroxyl value and viscocity were investigated. The product structure was characterized by FT - IR. The thermal property of rosin - based polyether polyol was compared with the other different types of polyols. The results showed that the heat resistance of rosin - based polyether polyol was higher than maleic rosin ester polyol and commercial polyether 4110. The introduction of hydroxymethyl rosin in rosin - based polyether polyol played an important role of the heat resistance. The higher mass fraction of hydroxymethyl rosin, the better heat resistance of rosin - based polyether polyol. The initial decompositon temperature of rosin - based polyether polyol with hydroxymethyl rosin as total starting material was up to 376.0 ℃.
