Abstract
A polyester wire varnish resin is the reaction product of (1) terephthalic acid or an ester-forming derivative thereof alone or in admixture with another dicarboxylic acid or an ester-forming derivative thereof (e.g. phthalic, isophthalic, maleic or succinic acid), (2) a dihydric compound comprising a mixture of a dihydric alcohol (e.g. ethylene glycol or propylene glycol) and 5-75 mol. per cent of a bis-phenol and (3) a compound containing more than three hydroxyl groups (e.g. glycerol or pentaerythritol). The molar ratio between (2) and (3) used is from 1:0,3 to 1:3 and the molar ratio between (1) and (2)+(3) used is such that the reaction mixture contains 1,2 to 3 hydroxyl groups for each carboxyl group (or its equivalent). Specified bis-phenols are 4:41-dihydroxydiphenyl, 2:2- bis-(p-hydroxyphenyl)-propane, 4:41-dihydroxy-diphenylsulphone and 4:41-dihydroxydiphenyl ether. Polyesterification may be effected in the presence of a catalyst such as an alkali, an alcoholate of an alkali metal, an alkaline earth metal or aluminium, an ester of boric or titanic acid or an organic salt of zinc, antimony, cerium or zirconium, the catalyst used in the examples being zinc resinate or a mixture thereof with antimony oxide. The polyesters are soluble in diacetone alcohol, methyl glycol acetate, xylene, cresol and phenol. They are made into wire varnishes by dissolving them in a mixture of xylenol or cresol and solvent naphtha or xylene and adding a hardening agent (e.g. an organic metal salt of zinc, cerium, zirconium, manganese, lead or cobalt or an organium titanium, aluminium or silicon compound). In the examples, butyl titanate is used as hardening agent together with zinc resinate as a flowing agent. In examples, polyesters were made by (1) Heating together dimethyl terephthalate, bis-phenol A, ethylene glycol and glycerine; (2) Heating together dimethyl terephthalate and bis-phenol A, adding ethylene glycol and glycerine and continuing the heating; (3) Heating together bis-phenol A and maleic anhydride, adding dimethyl terephthalate, 1:2-propylene glycol and glycerine and continuing the heating. Specification 775,082 is referred to.
