grams 0 5 moles of epichlorhydrin are added at a rate so as to maintain the temperature between 40 u00b0 c and 50 u00b0 c after addition is complete the epichlorhydrin is allowed to react for an additional 120 minutes at a temperature between 40 u00b0 c and 45 u00b0 c 550 cc of a 2 w w sulfuric acid solution are added and the temperature is raised to 60 u00b0 c and the reaction is allowed to continue for an additional 90 minutes the ph is then adjusted to between 3 5 and 6 and the solids content adjusted to 5 15 the overall reaction is shown in fig1 m n and p are moles of respective compound such that this example illustrates the reaction between a polyoxyalkylene diamine a dibasic acid of an aliphatic hydrocarbon and a polyamine 146 grams 1 0 moles of adipic acid 84 grams 0 8 moles of diethylene triamine and 180 grams 0 3 moles of jeffamine ed 600 u00ae a commercially available poly oxyalkylene diamine having the formula set forth in fig2 below wherein a c about 2 5 and b about 8 5 are charged to a 3 neck reaction flask equipped with a mechanical stirrer thermometer and water trap condenser the solution is heated to 160 u00b0 c.
