Flexible amine-epoxide resin and the controlled temperature preparation thereof
Abstract
Abstract AN ELASTOMERIC SOLID AMINE-EPOXIDE RESIN IS PREPARED FROM N,N''-DIMETHYLETHYLENEDIAMINE AND RESORCINOL DIGLYCIDYL ETHER. PREPARATION OF THE ELASTOMERIC RESIN INVOLVES MIXING THE DIAMINE AND DIGLYCIDYL ETHER IN PROPORTIONS TO PROVIDE AN AMINE HYDROGEN ATOM FOR EACH EPOXY GROUP OF THE DIGLYCIDYL ETHER, COOLING THE MIXTURE BEFORE VIGOROUS REACTION TAKES PLACE TO CAUSE IT TO BE AT A TEMPERATURE ABOUT 5*C., HOLDING THE MIXTURE AT SUCH A TEMPERATURE FOR ABOUT 5 HOURS, AND SUBJECTING THE RESULTING PARTIALLY REACTED MIXTURE TO HEAT AT ROOM TEMPERATURE TO FORM A VISCOUS LIQUID AMINE-EPOXIDE RESIN. THE VISCOUS LIQUID RESIN IS CURED BY HEATING AT AN ELEVATED TEMPERATURE TO PROVIDE THE ELASTOMERIC SOLID RESIN WHICH IS USEFUL AS AN ADHESIVE, A COATING, OR AS A CASTING RESIN.
