| titleOfInvention | Vinylpyrrolidone grafted polyolefins in polymer blends and composites |
| abstract | A thermoplastic composition comprising a first phase of a polar thermoplastic polymer, a second phase of nonpolar polyolefin incompatible with the latter, as well as a polyolefin grafted by vinylpyrrolidone at least at one interface in order to compatibilize the different phases. A mixed phase monomolecular layer of the composition which comprises ethylene vinyl alcohol copolymer mixed with vinylpyrrolidone grafted polypropylene as the first phase, and polypropylene as the second phase, has good water repellency and oxygen barrier properties. for applications in the packaging of food products. Also provided is a bondless, multi-layer laminate of the composition having an interlayer of a copolymer blend of ethylene-vinyl alcohol and vinylpyrrolidone-grafted polypropylene and outer layers of polypropylene. The laminate has good water repellency and oxygen barrier properties for food packaging applications. Further provided is a process for grafting vinylpyrrolidone onto polypropylene and polyethylene by mixing molten vinylpyrrolidone and polyolefin to be grafted in the presence of a free radical initiator for an effective time to obtain a vinylpyrrolidone graft product. . |
