摘　　要：以三羟乙基异氰尿酸酯(THEIC)为起始剂、三氟化硼.乙醚(BF3.OEt2)为催化剂,进行了环氧氯丙烷(ECH)聚合研究,考察了温度、时间及投料比等对ECH聚合可控性的影响,确定该体系下ECH可控聚合的优化条件为:n(BF3.OEt2)/n(ECH)/n(THEIC)为0.16/9~30/1;引发温度30~40℃,单体滴加时间10~15 h,室温下聚合时间10~12 h;n(ECH)/n(THEIC)为30/1是本体系ECH均聚的可控临界点,此时聚合反应总收率在90.0%以上,Mn在2680~2800左右,f为2.75~3.00。The controllability of polymerization of epoxy chloropropane(ECH) were studied,with trihydroxyethyl isocyanuricate(THEIC) as initiator and BF3·OEt2 as catalyst.The effect of reaction temperature,reaction time and ratio of materials on the controllability of ECH polymerization was tested.The optimizing reaction conditions were as follow,nBF3·OEt2/nTHEIC/nECH was 0.16/1/9~30/1,the temperature of initiation was 30~40℃,the dropping time of monomer was 10~15 h and the polymerize time was 10~12 h in room temperat...
