Abstract

A polyester, suitable for use as a plasticizer, is the polyesterification product of 1 : 5-pentane diol and a mixture of 25 to 50 molecular proportions per cent of adipic acid and 75 to 50 molecular proportions per cent of glutaric acid. Minor amounts of the glycol or dicarboxylic acids may be replaced by other glycols or dicarboxylic acids. Polyesterification is preferably effected in the absence of oxygen. The acids may be employed as their anhydrides, acid chlorides or alkyl esters and the glycol in the form of its acetate. Esterification catalysts (e.g. zinc chloride) or ester-interchange catalysts (e.g. stannous chloride, litharge, zinc acetate, calcium acetate, antimony trioxide or tetrabutyl titanate) may be used. The polyesters, which preferably have a viscosity of 10-5000 poises at 25 DEG C., are suitable for the plasticizing of polyvinyl chloride; copolymers of vinyl chloride and vinyl acetate, unsymmetrical dichloroethylene, styrene and the esters, nitriles and amides of acrylic, methacrylic, fumaric or maleic acid; synthetic rubbers, e.g. chloro-butadiene and butadiene-acrylonitrile polymers; chlorinated vinyl chloride polymers; chlorinated rubber; and cellulose derivatives, e.g. nitrocellulose, ethyl cellulose or cellulose acetate. The polyester may be mixed with vinyl chloride polymers or copolymers by milling the components together, as such, or in presence of an organic liquids which are swelling agents or solvents for one or both components. Alternatively solutions of the two components may be mixed. Fillers, pigments, other plasticizers, stabilizers or antioxidants may be added. The plasticized compositions may be formed into shapes or spread or calendered on a substrate. Examples disclose polyesters from (1)-(7) and (9)-(13) 1 : 5-pentane diol, glutaric acid and adipic acid, with or without methyl adipic acid, succinic acid, 1 : 2-propylene glycol, diethylene glycol, or a mixture of 1 : 2-propylene glycol and 2 : 2-dimethyl-1 : 3-propane diol; (8) 1 : 5-pentane diol, dimethyl glutarate and dimethyl adipate; (14) 1 : 5-pentane diol, diethylene glycol, dimethyl glutarate, dimethyl adipate and dimethyl phthalate. In Example (15), 50 parts of each of the above polyesters, 100 parts of polyvinyl chloride and 4 parts of calcium stearate are milled together at 165 DEG C. to effect gelation and a sheet obtained from the gel by pressing at 165 DEG C. followed by cooling under pressure.
