Claim:
A vinylidene chloride copolymer composition comprising: (A) at least one vinylidene chloride copolymer which is a copolymer composed of vinylidene chloride in an amount of at least 50 wt % and of at least one comonomer at least one of which is chosen from (meth)acrylic monomers corresponding to the general formula: CH 2 ═CR 1 R 2 in which R1 is chosen from hydrogen and the methyl radical and R 2 is the —CO—R 3 radical in which R 3 is the —O—R 4 radical with R 4 chosen from the linear or branched alkyl radicals containing from 1 to 18 carbon atoms optionally bearing one or more —OH radicals, epoxyalkyl radicals containing from 2 to 10 carbon atoms and alkoxyalkyl radicals containing a total of 2 to 10 carbon atoms; (B) from 0.5 to 4 parts by weight, per 100 parts by weight of (A), of epoxidized soybean oil; (C) from 0.01 to 2 parts by weight, per 100 parts by weight of (A), of at least one fluoroelastomer; and (D) from 0.05-1 part by weight, per 100 parts by weight of (A), of at least one acid scavenger, wherein said at least one fluoroelastomer (C) meets at least one of the following criteria: said at least one fluoroelastomer has a T g below 0° C.; said at least one fluoroelastomer has a heat of fusion of less than 1 J/g; and said at least one fluoroelastomer comprises more than 90 wt % of repeat units derived from one or more fluoromonomers.
