Abstract:
1. A method of making a chain extended in-situ polymerized nanonylon, suitable for extruding or molding without extensive processing alterations from processing conditions employed for a polymer targeted for replacement, comprising the steps of: (a) establishing via experimentation a viscosity/shear rate curve for the polymer targeted for replacement; (b) selecting an in-situ polymerized nanonylon having a given concentration of organoclay desired for improvement of performance properties; (c) selecting a chain extending agent for the nanonylon; (d) establishing reaction factors of the chain extending agent for the nanonylon; (e) using the reaction factors, reacting the in-situ polymerized nanonylon with the chain extending agent present at a given concentration sufficient to produce a chain-extended, in-situ polymerized nanonylon that has a viscosity/shear rate curve that essentially matches the viscosity/shear rate curve for the polymer targeted for replacement.
