<p>PROBLEM TO BE SOLVED: To provide a multi-layer structure with different organic polymer layers containing, in detail, a typical organic polymer layer and an acrylonitrile olefinic unsaturated polymer which contains no solvent nor water and can be melt-processed, and a multi-layer preparation method. SOLUTION: This multi-layer structure is formed of a layer containing an organic polymer composition and a layer containing an acrylonitrile olefinic (olefinically) unsaturated polymer which contains no solvent nor water and can be melt-processed. The unsaturated polymer contains about 50-95 wt.% of polymerizable acrylonitrile monomer and about 5-50 wt.% of at least, one kind of polymerizable olefinic unsaturated monomer. The organic polymer and the acrylonitrile olefinic unsaturated polymer are thermally stable to each other.</p> |
