Epoxidized diethanolamides were synthesized by reacting diethanolamine (DEA) with mixture of Epoxidized Palm Olein (EPOo ,40% w/w) and Refined Bleached Deodorized Palm Kernel Olein (RBDPKOo , 60% w/w) at 1:3 molar at 80°C for 5 h and continued at 110°C for another 4 h of reaction time. Synthesized diethanolamides with high content of epoxides were reacted with isocyanate in the presence of AlCl3-THF complex catalyst to produce oxazolidone linkages in polyurethane network. The rigid polyurethane foam produced is of better quality as compared to the commercially available foam.
