Multilayered structures

Abstract

A novel multilayer structure in which one layer comprises a polymer comprising a solventless, waterless, melt-processable acrylonitrile olefinically unsaturated polymer and the other layer comprises an organic polymer. Either polymer can be employed as the inner layer or the outer lays component of the multilayer structure.
