【摘要】 研究了三氟化硼·四氢呋喃(BF3·THF)催化三溴苯基缩水甘油醚/烯丙基缩水甘油醚/环氧丙烷/环氧乙烷共聚,合成侧链含有烯丙基的阻燃聚醚多元醇(HIROL Ⅲ)的方法。采用化学分析和仪器分析等对共聚物进行了确认。考察了反应物料比、催化剂等因素对共聚反应的影响。实验结果表明,三溴苯基缩水甘油醚和烯丙基缩水甘油醚的用量分别决定HIROL Ⅲ的含溴量和不饱和度高低,共聚反应温度和时间对合成HIROL Ⅲ影响较小。所得HIROL Ⅲ的溴质量分数达到23%～30%时,产品为淡黄色的透明液体,粘度为(1.06～1.17)Pa·s,Mn在1800～3200之间,羟值(57～69)KOHmg/g。更多还原

【Abstract】 The copolymer of tribromophenyl glycidyl ether allyl glycidyl ether,epoxypropane and oxirane was prepared using BF3·THF as catalyst.The process conditions were determined through the experiments such as catalyst,mass rate and reaction temperture.The experimental results indicated that the resulting HIKOLⅢ was lightyellowish liquid,its hydroxyl value and viscosity value were (57～69)?KOHmg/g and (1.06～1.17)?Pa·s,respectively,its bromine content was 23%～30%,and was suitable for preparing flameretardant soft PU foam.更多还原
