    Abstract: Poly(vinylfluoride) is heat stabilized by addition thereto of a poly(vinylpyridine), e.g., poly(4-vinylpyridine) poly(2-methyl-5vinylpyridine). From about 0.5 to 20 weight percent, now preferably 1 to 3 percent, approximately of the stabilizer is added to the poly(vinylfluoride) to protect it against thermal decomposition. Though poly(vinylfluoride) homopolymer decomposes rapidly in about 1 to 7 minutes at 260* C. and cannot be molded without use of a latent solvent, with the poly(vinylpyridine), decomposition does not occur at this temperature over a 30-minute period. This allows the polymer to be molded.
