POLY(VINYL CHLORIDE) POLYAMIDE MULTI-LAYER STRUCTURES

摘要

Improved poly(vinyl chloride) compositions which exhibit improved adhesivity to polyamide which find particular utility in the construction of multi-layer structures, particularly for the fabrication of improved structures for use in forming electrical insulation structures for wires and cables. In one useful embodiment, the multi-layer structure has in the following order: a layer of PVC and a layer of polyamide in contact with the layer of PVC wherein the layer of PVC includes a vinyl chloride containing copolymer or a terpolymer which exhibits good solubility with the PVC, and which further provides good adhesivity with the PA. The vinyl resin is selected from the group consisting of vinyl chloride-vinyl acetate-vinyl alcohol terpolymers.
