Imines and secondary amines containing hydrogen bonding moieties in their backbone and polymers made therefrom

摘要

Imines and secondary amines comprising a backbone portion containing a plurality of polyalkyleneoxy moieties and one or more internal urea, thiourea, biuret, thiobiuret, amide, or thioamide moieties, and a plurality of imino or secondary amino end groups, wherein each imino or secondary amino end group is separated from a urea, thiourea, biuret, dithiobiuret, amide, or thioamide moiety by at least one alkylene, cycloalkylene, aralkylene, arylene, alkyleneoxy, or ppolyalkyleneoxy moiety are disclosed. Prepolymers and polymers prepared from the imines and secondary amines are also disclosed. In addition, the imines and secondary amines of the invention are also useful as epoxy resin curing agents.
