Abstract

Synthetic resins are prepared by condensing a phenol-carboxylic acid with a methylene-containing agent in the absence of a catalyst or in weakly acid or alkaline conditions and reacting the product with a polyhydric alcohol. Alternatively, the phenol-carboxylic acid, the methylene-containing agent and the polyhydric alcohol may all be reacted together. The compatibility with oils may be improved by combining with the resin at any stage or stages a modifying agent such as a natural resin, fatty oils or fatty acids. Modifying agents which may also act as plasticizers include castor oil, linseed oil, tung oil, cottonseed oil, coconut oil, soya bean oil or the corresponding fatty acids, blown or polymerized oils, rosin, abietic acid, dibutyl phthalate, tricresylphosphate, acetanilide, toluene sulphonamide, and ethyl or methyl phthalylglycollate. The products with or without the addition of metallic driers and oil-soluble synthetic resins such as phenylphenolformaldehyde condensation products may be used in oil or cellulose ester coating compositions. In examples: (1) a phenolcarboxylic acid such as salicylic acid, cresotinic acid, dihydroxybenzoic acid, gallic acid, hydroxyphthalic or hydroxynaphthoic acids is condensed with a methylene-containing body such as formaldehyde, paraform, hexamethylenetetramine, furfurol, acetaldehyde or acetone in the presence, if desired, of a weak or dilute acid such as oxalic acid, and the product is interacted with (a) a polyhydric alcohol such as glycerol, polyglycerol, glycol, ethylene glycol or pentaerythritol, (b) a mixture of abietic acid and glycerine, (c) firstly a polybasic acid such as phthalic anhydride, maleic acid or succinic acid and after with glycerine, or (d) a mixture of castor oil and glycerine, to yield a resinous product; (2) p-hydroxybenzoic acid or p-cresotinic acid is condensed with formaldehyde in the presence of oxalic acid, or salicylic acid is condensed with formaldehyde in the presence of lime, and the products are interacted with a mixture of rosin and glycerine; (3) p-hydroxybenzoic acid is condensed with formaldehyde in the presence of oxalic acid and the product is heated with rosin and then with phthalic anhydride, glycerol and linseed oil, tung oil or sunflower seed oil fatty acids.
