Abstract
A composition and process are provided for making precipitated biconstituent nylon-polyvinyl alcohol shaped articles by dissolving polyvinyl alcohol and a nylon having an amide group index of less than about 145 in a mixture of a tertiary amine oxide solvent and water, with the solution containing from about 3.0 to about 11% water, to form a biconstituent dispersion wherein the nylon and the polyvinyl alcohol comprise distinct separate phases. Shaped articles can be formed from the biconstituent dispersions of the invention.
