Epoxidized poly amides

Claim 1

IN MAKING A WATER SOLUBLE ETHENOID BOND POLYMERIZABLE MONOMER CONTAINING TERMINAL AMIDE GROUPS AND A GLYCIDYL ETHER GROUP ATTACHED TO AND PENDANT FROM A SECONDARY AMINE GROUP, THE KPROCESS WHICH COMPRISES FORMING A MIXTURE OF (1) 1 MOLE OF OF AN ALKYLENE POLYAMINE, HAVING 2-4 CARBON ATOMS PER ALKYLENE UNIT, TWO TERMINAL PRIMARY AMINE GROUPS AND AT LEAST ONE INTERMEDIATE SECONDARY AMINE GROUP, AND (2) 0.9-1.6 MOLES OF AN ALPHA-UNSATURATED C4-C10 ALIPHATIC POLYCARBOXYLIC ACID, THE PROPORTION OF SAID ACID BEING SO SELECTED WHEN THE RANGE STATED AS TO PROVIDE THE ACID IN AMOUNT LESS THAN EQUIVALENT TO ALL AMINE GROUPS AND LEAVE AT LEAST ONE SECONDARY AMINE GRUP, HEATING THE RESULTING PRIMARY AMINE SALT HAVING THEREIN UNREACTED SECONDARY AMINE GROUP AT A TEMPERATURE ABOVE THE BOILING POINT OF WATER UNTIL SAID SALT IS DECOMPOSED TO AMIDE GROUP AND NO SUBSTANTIAL AMOUNT OF ADDITONAL WATER IS LIBERATED, THEN ADMIXING EPICHLOROHYDRIN IN THE PROPORTION OF ABOUT 0.4-3 MOLES FOR EACH MOLE OF SAID ACID USED, AND WARMING THE RESULTING MIXTURE AT A TEMPERATURE OF AT LEAST 50*C. UNTIL THE REACTION THAT ENSUES BETWEEN THE UNREACTED SECOND-I ARY AMINE GROUP AND THE EPICHLOREHYDRIN IS A SUBSTANTIALLY COMPLETED AND THE PH HAS FALLEN TO A SUBSTANTIALLY CONSTANT LEVEL.
