Abstract
METHYLENE BIS O-CHLORO ANILINE HAS LONG BEEN RECOGNIZED AS A SUPERIOR URETHANE CURATIVE BUT TOXICITY CONCERNS HAVE LIMITED ITS USE. ALTERNATIVE COMPOUNDS ARE AVAILABLE, BUT THEY CANNOT MATCH THE HANDLING AND ULTIMATE PHYSICAL PROPERTIES OF MOCA CURED ELASTOMERS. AN INVESTIGATIONS OF NOVEL PLYAMINE AND POLYOL COMPOUNDS SHOULD YIELD NEW AND USEFUL URETHANE CURATIVES. THE PROGRAM WOULD IN VOLVE SCREENING MODIFIED POLYAMINE AND POLYOL COMPOUNDS AS CURATIES FOR TDI TERMINATED URETHANE PREPOLYMERS. AMINE CURATIVES WILL BE MODIFIED BY TWO MEANS: CHEMICAL AND PHYSICAL METHODS. CHEMICAL MODIFICATIONS WILL BE MOLECULAR STRUCTURE CHNAGES DESIGNED TO IMPROVE ULTIMATE PHYSICAL PROPERTIES, IMPROVE CURATIVE-PREPOLYMER COMPATIBILITY, LOWER THE CURATIVE MELTING POINT, OR MODIFY ITS REACTIVITY. PHYSICAL MODIFICATIONS WILL INVOLVE BLENDING CURATIVES TO ACHIEVE THE SAME OBJECTIVES. POLYOL CURATIVES WILL BE EVALUATED UNMODIFIED, BUT IN COMBINA TION WITH CATALYSTS AND/OR DIPHENYL METHANE DIISOCYANATE TO IMPROVE PHYSICAL PROPERTIES AND PROCESSING CHARACTERISTIS. CURATIVE SYSTEMS WILL BE EVALUATED BY DETERMINING POT LIFE, DE MOLD TIME, AND PHYSICAL PROPERTIES OF CURED ELASTOMERS. THE CURATIVES WILL BE COMPARED TO MOCA CONTROLS. THE GOAL OF THIS EFFORT IS TO DEMONSTRATE THAT NOVEL, NON-TOXIC CURATIVES CAN REPLACE MOCA, WHILE STILL PROVIDING MOCA'S DESIRABLE PRO CESSING AND HANDLING PROPERTIES.
