Abstract:
1. A multi-layer blown film article comprising a coextruded layer of chain-extended nanonylon, wherein the chain-extended nanonylon comprises a concentration of organoclay of greater than about 3 percent by weight and less than about 8 percent by weight of the chain-extended nanonylon, wherein the chain-extended nanonylon is the reaction product of an in-situ polymerized nanonylon and a chain extending agent selected from the group consisting of carbodiimides, carbodiimide hydrochlorides, multi-functional epoxies, carbonylbiscaprolactames, multi-functional acrylic oligomers, and combinations thereof and, wherein the weight average molecular weight of the in situ polymerized nanonylon has been increased from about 50,000 to 80,000 to from about 85,000 to about 110,000.
