Polyether-type isocyanate prepolymers are prepared with polyether polyols and tolylene diisocyanate.
采用聚醚多元醇和甲苯二异氰酸酯合成了聚醚型异氰酸酯预聚体。
The results showed that the terminated prepolymer was prepared by introducing ethylene glycol alkyl ether as a capping agent into the reaction system of castor oil and tolylene diisocyanate (TDI).
结果表明，采用蓖麻油与甲苯二异氰酸酯（TDI）反应，加入封端剂乙二醇烷基醚类，得到封端型聚氨酯预聚体。
