Abstract
A composition and process are provided for making precipitated biconstituent nylon-cellulose shaped articles by dissolving a nylon having an amide group index of less than about 145, in a mixture of a tertiary amine oxide solvent and water, containing from about 0.5% to about 11% water based on the weight of the solution; separately forming a solution of cellulose in a tertiary amine oxide solvent containing from about 0.8 to about 29% water based on the weight of the solution and then interdispersing the two solutions to form a biconstituent dispersion. Shaped articles can be formed from the biconstituent dispersions of the invention.
