Compatible blends of polyvinylidene fluoride and aromatic polyimide

摘要

A compatible alloy of superior mechanical strength, hardness and abrasion or mar resistance comprising PVDF and at least one compatible aromatic polyimide . The aromatic polyimide in the alloy system acts as a nucleating agent for PVDF crystallization. The alloy system comprising PVDF and aromatic polyimide does not exhibit the negative characteristic of reduced mechanical strength encountered in PVDF and polymer alloys known in the art. The PVDF/aromatic polyimide alloy is prepared by dissolving, separately, PVDF and the aromatic polyimide in a solvent and blending the solutions to form the required composition.
