| abstract | 1,136,814. Water-dispersible polyesters. ASHLAND OIL & REFINING CO. 17 Jan., 1966 [4 Aug., 1965], No. 2123/66. Heading C3R. Water-dispersible polyester resins are made by reacting to an acid number of not more than 30, (a) an aromatic dicarboxylic acid or anhydride thereof, (b) a saturated aliphatic dicarboxylic acid or anhydride thereof (preferably containing 4 to 10 carbon atoms), (c) a polyethylene glycol or polypropylene glycol of molecular weight 600 to 6000 and (d) a different polyhydric alcohol containing 2 to 16 carbon atoms; the polyalkylene glycol (a) accounting for 1 to 10 mole per cent of the total polyols (a) + (b). Specified aromatic dicarboxylic acids are ortho-, iso- and tere-phthalic acids, chlorophthalic acid and chlorendic acid. Specified polyhydric alcohols are ethylene glycol, diethylene glycol, trimethylene glycol, neopentylene glycol, 2:2:4-trimethyl-1:3-pentanediol, hydrogenated bisphenol A, glycerine, pentaerythritol, dipentaerythritol, trimethylol ethane, trimethylol propane, sorbitol, mannitol nd inositol-mixtures of dihydric and higher <SP>a</SP>olyhydric alcohols may be used. Polyesterification is effected at 350-575‹ F. in one or more stages. Salts of the polyesters and potassium hydroxide, primary, secondary or tertiary amines or alkanolamines are dispersible in water possibly containing a co-solvent, e.g. " Cellosolve " (Registered Trade Mark) or its acetate, carbitol, butyl carbitol or tertiary butanol. Coating compositions are made by adding a cross-linking resin to the aqueous dispersion, e.g. a phenol-formaldehyde, urea-formaldehyde or melamine-formaldehyde condensate. In examples the polyesters are made by reacting (a) isophthalic acid, (b) adipic acid, (c) polyethylene glycol of molecular weight 1450 and (d) a mixture of trimethylol ethane and hydrogenated bisphenol-A or neopentylene glycol. |
