Abstract

The invention comprises polyesters of the formula P-COO-[-R1.OOC.R.COO-]-nR1.OOC.P where R is a saturated aliphatic hydrocarbon chain containing at least 2 carbon atoms, R1 is a saturated aliphatic carbon chain containing at least 3 carbon atoms, P is the hydrocarbon chain of pelargonic acid, and n is 6-8. They are prepared by heating the appropriate dicarboxylic acid with a small proportion of pelargonic acid and an excess of the diol, HO.R1.OH, until esterification is complete, then removing excess diol. Suitable diols are propane diol-1,2, the butane diols, and neopentyl glycol, and suitable dicarboxylic acids are adipic, sebacic, and azelaic. An example describes the preparation of a polyester from 7 moles of adipic acid, 2 moles of pelargonic acid, and 10 moles of propanediol-1,2. The polyesters are used as plasticizers in compositions of vinyl chloride polymers and copolymers.ALSO:The invention comprises polyesters of the formula P.COO-[-R1.OOC.R.COO-]-nR1.OOC.P, where R is a saturated aliphatic hydrocarbon chain containing at least 2 carbon atoms, R1 is a saturated aliphatic hydrocarbon chain containing at least 3 carbon atoms, P is the hydrocarbon chain of pelargonic acid, and n is 6 to 8, and compositions of polymers and copolymers of vinyl chloride containing the same as plasticizers. The polyesters are prepared by heating together a saturated aliphatic dicarboxylic acid containing at least 4 carbon atoms, an excess of a saturated aliphatic diol containing at least 3 carbon atoms, and a small proportion of pelargonic acid until esterification is substantially complete, then removing excess diol. The compositions with vinyl chloride polymers and copolymers usually contain a stabilizer for the same, e.g. dibasic lead phthalate. Suitable diols are propanediol-1,2, the butane diols and neopentyl glycol, and suitable dicarboxylic acids are adipic, sebacic and azelaic. An example describes the preparation of a polyester from 2 mols of pelargonic acid, 7 mols of adipic acid and 10 mols of propanediol-1,2, and its incorporation as plasticizer into an insulating composition comprising 100 parts by weight of polyvinyl chloride, 60 p.b.w. of polyester and 6 p.b.w. of dibasic lead phthalate, which is then compared with a similar composition using a lauric acid stopped polyester.
