    • Polyurethanes with pendant reactive 2-cyanoacetamide moieties derived from a reaction mixture of: a) at least one 2-cyanoacetamido-substituted compound selected from 2-cyanoacetamido-substituted glycol, 2-cyanoacetamido-substituted aromatic diol, aliphatic or aromatic 2-cyanoacetamido-substituted polyol, 2-cyanoacetamido-substituted monohydroxy alcohol or phenol; and b) at least one diisocyanate or polyisocyanate. (2-Cyanoacetamido) alcohols with a hydroxy functionality other than 2 lead to polyurethanes with terminal 2-cyanoacetamido moieties and/or branch sites with 2-cyanoacetamido moieties. The polyurethanes are useful for coatings and in industries where polymers with enhanced physical properties are sought.
    • 具有衍生自以下的反应混合物的侧链反应性2-氰基乙酰胺部分的聚氨酯:a)至少一种2-氰基乙酰氨基取代的化合物,其选自2-氰基乙酰氨基取代的二醇,2-氰基乙酰氨基取代的芳族二醇,脂族或芳族2-氰基乙酰氨基 - 取代的多元醇,2-氰基乙酰氨基取代的一羟基醇或苯酚; 和b)至少一种二异氰酸酯或多异氰酸酯。 具有除2以外的羟基官能团的(2-氰基乙酰胺基)醇导致具有2-氰基乙酰氨基部分末端和/或具有2-氰基乙酰氨基部分的分支位点的聚氨酯。 聚氨酯可用于涂料和在具有增强物理性能的聚合物的工业中。
