Abstract
Chain-extended nanonylon is made from the reaction of oligomeric nanonylon and chain-extending agents. Such chain-extended nanonylon contains concentrations of organoclay exceeding 10 weight percent. High concentrations of organoclay permit the chain-extended nanonylon to be used as either a concentrate or a compound that provides good barrier properties for thermoplastic articles made from the chain-extended nanonylon.
Claims18
A process for converting oligomeric nanonylon into chain-extended nanonylon, comprising the step of reacting the oligomeric nanonylon, having an organoclay concentration of greater than 10 percent, with a chain extending agent, selected from the group consisting of carbodiimides, carbodiimide hydrochlorides, multi-functional epoxies, carbonylbiscaprolactames, multi-functional acrylic oligomers, and combinations thereof, to form the chain-extended nanonylon.
The process of claim 4, wherein the molecular weight of the oligomeric nanonylon ranges from about 25,000 to about 35,000.
A chain-extended nanonylon have a concentration of organoclay exceeding 10 percent by weight of the chain-extended nanonylon, wherein the chain-extended nanonylon is the reaction product of an oligomeric 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.
