The Effect of the Content of Polyurethane and Dispersant on the Impact Strength and Adhesability of Polyurethane/Polypropylene Composition
Polyurethane (PU) /polypropylene (PP) composition in which PU fine particles were dispersed homogeneously in PP was prepared by the bulk reaction of 4, 4′-diisocyanatodiphenylmethane with a diol mixture (molar ratio=1: 2) of poly (ethylene) adipate diol (Mn=2000) and ethylene glycol in situ in a mel...

Zusammenfassung: | Polyurethane (PU) /polypropylene (PP) composition in which PU fine particles were dispersed homogeneously in PP was prepared by the bulk reaction of 4, 4′-diisocyanatodiphenylmethane with a diol mixture (molar ratio=1: 2) of poly (ethylene) adipate diol (Mn=2000) and ethylene glycol in situ in a melted PP. Effects of the content of polyurethane and dispersant on impact strength and adhesability of the composition were determined. Impact strength and adhesability of the PU/PP composition were improved considerably by using 40wt% polyurethane and 5wt% dispersant. |
