The present invention relates to a formulated vinylidene copolymer composition comprising a copolymer of vinylidene chloride with an alkyl acrylate and/or vinyl chloride and a metal silicate and a metal hydroxide stabilizer represented by the formula: Cai.x.y M 2+x Aly (OH)2 wherein M2+ represents at least one bivalent metal selected from the group consisting of Mg, Zn, or Cu, preferably Mg and/or Zn, x is in the range of 0 < x < 1, preferably 0 < x < 0.4 and y is in the range of 0 < y < 0.1 an one or more of the following additives: a high density polyethylene, an epoxidized vegetable oil, an oxidized polyolefin, and/or a paraffin or polyolefin wax. The formulated vinylidene copolymer composition demonstrates substantially improved heat stability than existing compositions. |
