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.
