Abstract: The invention relates to plasticizer compositions for polyvinyl chloride resins. A plasticized polyvinyl chloride resin contains (a) 100 parts by weight of at least one polyvinyl chloride resin and (b) 0.1 to 200 parts by weight of a plasticizer compounded with the polyvinyl chloride resin, 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 contain 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, the fatty acid can be saturated or olefinically unsaturated, linear or branched.
Abstract: The invention is a plasticizer for nitrocellulose based resins, a method for plasticizing a nitrocellulose based resin and a nitrocellulose based paint containing the plasticizer. The plasticizer contains a mixture of (i) at least one isobutanol ester of a fatty acid with 8 to 24 carbon atoms. The acids can be saturated or unsaturated, linear or branched, and contain at least one epoxy group per molecule and (ii) at least one methyl ester of a fatty acid with 16 to 18 carbon atoms which acids can be saturated or olefinically unsaturated, linear or branched.
