There are disclosed novel halogenated polymer compositions comprising (a) 100 parts of a chlorinated thermoplastic, (b) 0.7 to 2 parts of thiodiethylene glycol bis (acetoacetate) of formula (H3CCOCH2COOCH2CH2)2S, (c) 0 to 0.5 part of at least one calcium, barium and/or magnesium salt of an aliphatic C8-C24 monocarboxylic or C8-C24 hydroxymonocarboxylic acid or of benzoic acid or tert-butylbenzoic acid, (d) 0.01 to 0.2 part of at least one zinc salt of an aliphatic C8-C24monocarboxylic or C8-C24hydroxymonocarboxylic acid or of benzoic acid or tert-butylbenzoic acid, (e) 3 to 10 parts of epoxidised unsaturated fatty acid esters, and (f) 10 to 70 parts of at least on organic plasticiser. These compositions can be used, in particular, for the preparation of PVC sheets for food packaging. |
