## Abstract The phase‐separation behavior and morphology of polycarbonate‐based polyurethanes were investigated as a function of the soft‐segment molecular weight and chemical structure and the 4,4′‐diphenylmethane diisocyanate/1,4‐butanediol based hard‐segment contents. Polarized optical microscop
## Abstract Structural and mechanical data have been compared for reaction injection molding (RIM) polyurethanes prepared from uretonimine‐modified diphenylmethane 4,4′‐diisocyanate (MDI), ethylene glycol (EG), and a polyol (a polyether; __M__~__n__~ ≃ 5000), in order to investigate the effect of a
