Abstract

1445892 Polyesters CIBA-GEIGY AG 14 Dec 1973 [19 Dec 1972] 58077/73 Heading C3R Saturated curable polyesters based on aromatic dicarboxylic acids, saturated diols, and optionally, a minor amount of polyols and/or polycarboxylic acids that are more than bifunctional have (a) a hydroxyl number of from 10-35 mg. of KOH per gram of polyester, (b) an intrinsic viscosity of from 0À26-0À40 dl./g. measured on a 1% solution in a 1 : 1 mixture of phenol/tetrachloroethane at 30‹ C., and (c) a melting range of from 90-130‹ C. The polyesters in the preferred embodiment and in the examples are prepared by transesterification and subsequent polycondensation from dimethylterephthalate, 30-65 mol. per cent of neopentyl glycol, 4-10 mol. per cent of bisoxyethylated 4,4<SP>1</SP> - dihydroxydiphenyl - 2,2- propane, 0À1-2 mol. per cent pentaerythritol and/or trimethylolpropane, the mol. per cent being based on the amount of dimethylterephthalate used, and sufficient ethylene glycol to make the initial molar ratio of dimethylterephthalate to the sum of the diol and polyol equal to 1 : 1À8-1 : 2À3. The polyesters can be used to make pulverulent coatings comprising a cross-linking agent preferably a masked diisocyanate such as an isophorone-diisocyanate masked with #-caprolactam, and titanium dioxide which can be coated on to various substrates, e.g. metals using an electrostatic powder spraying apparatus, which are then cured by heating.
