Title: Method to establish viscosity as a function of shear rate for in-situ polymerized nanonylon via chain extension

Abstract: Chain-extended nanonylon is made from the reaction of in-situ polymerized nanonylon and chain-extending agents. Knowing the viscosity/shear rate curve for a thermoplastic polymer to be replaced, such as nylon, the method of the present invention allows via adjustment of organoclay concentration and chain extension of the nylon polymer and other reaction factors to achieve a chain-extended, in-situ polymerized nanonylon to have a viscosity/shear rate curve that essentially matches the viscosity/shear rate curve for that neat nylon within a commercially operable shear rate.
