摘　　要：利用3-异丙基-二甲基苄基异氰酸酯(TMI)分别与3种聚醚多元醇反应合成了3种大分子单体分散剂(以下简称大分子单体),发现用高官能度聚醚ZS-6600合成得到的大分子单体T01合成的聚合物多元醇(POP)黏度最低。考察了合成温度、时间及催化剂对T-01的物化性能和应用于合成POP的影响,将由T-01合成的POP和其它分散剂合成的POP分别制备聚氨酯泡沫,比较POP和泡沫的性能。结果表明,T-01分散剂合成的POP制备的聚氨酯泡沫各项物理性能都能达到或优于传统POP制备的泡沫。Three kinds of macromonomer dispersant(hereinafter referred to as macromonomers)were synthesized by reacting 3-tolyl-dimethylbenzyl isocyanate(TMI)with three different polyether polyols,respectively.It was found that the polymer polyol(POP)synthesized from the macromonomer T-01 synthesized with the high-functionality polyether ZS-6600 had the lowest viscosity.The effects of synthesis temperature,time and catalyst on the physical and chemical properties of T-01 and its application in POP were investigated.The results showed that all the physical properties of polyurethane foam prepared from POP synthesized by T-01 dispersant could reach or exceed polyurethane foam prepared from traditional POP.
