Vinylpyrrolidone grafted polyolefins in polymer blends and composites

摘要: A thermoplastic composition containing a first phase of polar polymer, second non-polar polyolefin incompatible therewith, and vinylpyrrolidone grafted at least an interface to compatibilize the different phases. mixed monolayer ethylene-vinyl alcohol copolymer blended with polypropylene as phase, has good oxygen moisture barrier properties for food packaging applications. Also disclosed is tieless multilayer laminate having interlayer blend outer layers polypropylene. The Further method grafting onto polyethylene by melt blending be in presence free radical initiator time effective obtain product.
