抄録

Four types polyurethanes were synthesized using PCL oligomers with similar molecular weight and different molecular weight distributions and 4, 4′ -diphenylmethane diisocyanate (MDI) as chain extender: Poly (narrow), Poly (wide), Poly (narrow+wide), and Poly (narrow) + Poly (wide). The crystallization behavior of the polyurethanes was studied by DSC, tensile test, and WAXD. The crystallinities of the polyurethanes were in the following order: Poly (wide) >Poly (narrow) +Poly (wide) >Poly (narrow+wide) >Poly (narrow). The present study shows the importance of the distribution of caprolactone chains and their combination in the polyurethane.
