Polyester polyalcohols containing amino and amide groups and poly (urea) urethane produced therefrom |
摘要 |
A process for the manufacture of polyester polyalcohols with amino and amide groups by the reaction of polyester polyalcohols with polyamines is characterized in that unsaturated polyester polyalcohols if necessary in admixture with saturated polyester polyalcohols are used as polyester polyalcohols, and low molecular weight, aliphatic polyamines with two primary amino groups are used as polyamines.
