Plasticized poly vinyl chloride compositions

A plasticized polyvinyl chloride composition comprising:(a) 100 parts by weight of at least one polyvinyl chloride resin and (b) 0.1 to 200 parts by weight of a plasticizer wherein the plasticizer comprises (i) at least one isobutanol ester of a fatty acid with 8 to 24 carbon atoms, wherein, the fatty acid can be saturated or olefinically unsaturated, linear or branched and contains at least one epoxy group per molecule and (ii) at least one methyl ester of a fatty acid with 16 to 18 carbon atoms, wherein, these fatty acids can be saturated or olefinically unsaturated, linear or branched.

A plasticizer composition for polyvinyl chloride resins comprising (i) at least one isobutanol ester of a fatty acid with 8 to 24 carbon atoms, wherein, the fatty acid can be saturated or olefinically unsaturated, linear or branched and contains at least one epoxy group per molecule and (ii) at least one methyl ester of a fatty acid with 16 to 18 carbon atoms, wherein, these fatty acids can be saturated or olefinically unsaturated, linear or branched.

A method of plasticizing a polyvinyl chloride resin which comprises:

• incorporating a plasticizing effective amount of a plasticizer comprising (i) at least one isobutanol ester of a fatty acid with 8 to 24 carbon atoms, wherein, the fatty acid can be saturated or olefinically unsaturated, linear or branched and contains at least one epoxy group per molecule and (ii) at least one methyl ester of a fatty acid with 16 to 18 carbon atoms, wherein, these fatty acids can be saturated or olefinically unsaturated, linear or branched.
