CURING AGENT FOR USE IN MAKING CELLULAR POLYURETHANE COMPOSITIONS

摘要

By reacting a proper proportion of an alkylene oxide with methylene dianiline (MDA), there is obtained a curing agent or cross-linking agent useful in place of methylene-bis-orthochloro aniline (MOCA) for making polyurethane foams. The invention provides a solution to the problem of finding a substitute for MOCA, which has become suspected as a carcinogen.
