METHOD OF MAKING ORGANIC AMINES CONTAINING HYDROXYALKYL CARBAMATE GROUPS

摘要

ORGANIC AMINES CONTAINING HYDROXYALKYL CARBAMATE GROUPS AND METHOD OF MAKING THE SAME Novel compounds comprise a secondary amine containing one or more hydroxyalkyl carbamate groups. The compounds are obtained by reaction of a cyclic carbonate such as ethylene or propylene carbonate with a primary amine group of a multi-functional amine containing at least one primary amine group and at least one secondary amine group which is inhibited from reacting with the carbonate. The secondary amine groups, by surviving the reaction with the cyclic carbonate, remain free to react with functional sites on suitable backbone polymers to anchor the hydroxyalkyl carbamate groups thereon. These polymers may then be selfcross-linked through hydroxyalkyl carbamate groups. In addition, the compounds of the invention can self-condense to form coatings which are resistant to organic solvents.
