Abstract
Abstract A NEW MONOMER TRIACRYLYDIETHYLENETRIAMINE IS PREPARED BY THE REACTION OF DIETHYLENETRIAMINE ACRYL CHLOFRIDE AND SODIUM HYDROXIDE, THE REACTION YIELDING THE DESIRED MONOMER, SODIUM CHLORIDE AND WATER. THE MONOMER, TRIACRYLYDIETHYLENETRIAMINE IS USEFUL IN THE PHOTOPOLYMERIZATION PROCESS AS HIGH SPEED POLYMERIZABLE MONOMER IN CONJUCTION WITH A COLLODIAL CARRIER AND A LIGHT SENSITIVE FERRIC SALT. MODIFICATION OF THE REACTANTS IN THE ABOVE PROCESS ALLOW FOR THE PRODUCTION OF POLYACRYLYL AND POLYMETHACRYLYL POLYETHYLENE POLYAMINES CONTAINING 2 TO 4 EHTYLENE GROUPS.
