Polyurethanes using novel N-substituted perhydrodioxazepines as catalysts

摘要

A primary amine may be reacted with formaldehyde and a 1,2-diol to produce N-substituted perhydrodioxazepines of the formula <IMAGE> where R is alkyl, alkoxyalkyl, aminoalkyl or aryl alkyl and R' is hydrogen or lower alkyl. These compounds may be easily prepared and have a low odor which is essential in their utility as polyurethane catalysts. By varying the R group, the catalytic characteristics of the compounds may be altered as desired.
