The target of this research was to prepare rigid polyurethane foams
catalyzed by metal-amine complexes; M(en)2, M(trien) and metal-amine-salicylate
complexes; M(en)2Sal2, M(trien)Sal2. It was expected that the synthesized metal
complexes showed good catalytic activity and the desirable physical and mechanical
properties of prepared foams were presented. Moreover, the reaction times during
foam preparation, the physical and mechanical properties of foams were studied by
varying catalyst types, the amount of catalysts and blowing agent, and NCO indexes.
