Abstract

Mono (aromatic urethane) substituted organic isocyanates resulting from the reaction of approximately equal molecular proportions of a polyisocyanate and a monohydric phenol (see Group IV (b)) are used as curing or cross linking agents in diisocyanate modified polyesters and polyesteramides. Specified mono adducts include those formed from mono-alpha-phenyl ethyl phenol and 4:41-diphenyl diisocyanate, 1-methyl-2:4-phenylene diisocyanate, 1:5-naphthalene diisocyanate or hexamethylene diisocyanate. Many other phenols and polyisocyanates are specified.ALSO:The invention comprises mono-(aromatic urethane) substituted organic isocyanates and their preparation by reacting approximately equimolecular amounts of an organic polyisocyanate and a monohydric phenol, the hydroxyl group in the phenol being the only group in either reactant which possesses a reactive hydrogen atom. Specified polyisocyanates include aliphatic diisocyanates such as hexamethylene diisocyanate, aromatic polyisocyanates such as the 4 : 41-diphenyl, 1-methyl-2 : 4-phenylene, and 1 : 5-naphthalene diisocyanates and cycloaliphatic polyisocyanates. Specified phenols include phenol, the alkyl substituted phenols, the chloro and nitro phenols and aralkyl substituted phenols such as mono-alpha-phenyl ethyl phenol. Preferably the reaction is carried out by dissolving the phenol and an excess of the polyisocyanate in an inert solvent and allowing to stand. An example describes the preparation of the mono-adduct of 4 : 41-diphenyl diisocyanate and mono-alpha phenyl ethyl phenol.
