Abstract

1,158,841. Polyesters containing oxazoline and imide groups. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 31 Jan., 1967 [14 April, 1966], No. 16431/66. Heading C3R. Thermosetting resins are made by (a) reacting at least one primary amine containing at least two hydroxyl groups one of which is in vicinal relationship to the amino group with one or more polycarboxylic acids to produce at least one hydroxycarboxylic acid containing at least one oxazoline ring between functional groups, (b) forming a reaction mass comprising the oxazoline ring-containing hydroxycarboxylic acid, at least one polycarboxylic acid and at least one polyhydric alcohol, in which reaction mass at least one imide ring is included between functional groups of a hydroxycarboxylic acid or a polycarboxylic acid and (c) heating the reaction mass to effect esterification and resinification. Specified hydroxyamines are those of formula where R<SP>111</SP> is hydrogen or an organic radical and R<SP>1</SP> and R<SP>11</SP> are organic radicals at least one of which contains a hydroxyl group, preferred hydroxyamines being tris(hydroxymethyl)- aminomethane and/or 2-amino-2-methyl-1:3- propanediol. Specified polycarboxylic acids are terephthalic acid, isophthalic acid, an imidecontaining polycarboxylic acid derived by reacting 1 mol of trimellitic anhydride with 1 mol of p-aminobenzoic acid, and imide-containing polycarboxylic acids derived by reacting 2 mols of trimellitic acid with 1 mol of a diprimary amine. Specified polyhydric alcohols are (i) those of formula where a = 1-3, b = 1-3, c = 1-3, n = 1 or 2, m = 0 or 1, X is an aromatic radical radical (especially phenylene or xylylene) and R<SP>1</SP>, R<SP>11</SP> and R<SP>111</SP> are aliphatic, cycloaliphatic or heterocycloaliphatic radicals, and (ii) those of formula where R<SP>1</SP>, R<SP>11</SP> and R<SP>111</SP> are aliphatic, cycloaliphatic or heterocycloaliphatic radicals and a, b and c are 1, 2 or 3. The alcohol components of the above may be derived from ethylene glycol, propylene glycol, neopentyl glycol, 1:4-cyclohexanedimethanol, glycerol, trimethylol ethane, trimethylol propane, pentaerythritol or tris(2-hydroxyethyl)isocyanurate. The polymers when dissolved in a solvent (e.g. cresol, xylol and naphtha) and after addition of a catalyst (e.g. tetracresyl titanate) are useful as wire enamels. In examples, the polymers were formed from (1) dimethyl terephthalate, ethylene glycol, tris(hydroxymethyl)aminomethane, isophthalic acid, 4:4<SP>1</SP>-diaminodiphenyl methane and trimellitic anhydride; (2) dimethyl terephthalate, ethylene glycol, 4:4<SP>1</SP>-diaminodiphenyl methane, trimellitic anhydride and tris(hydroxymethyl)aminomethane ; (3) dimethyl terephthalate, ethylene glycol, tris(2-hydroxyethyl)isocyanurate, tris(hydroxymethyl)aminomethane, isophthalic acid, 4:4<SP>1</SP>- diaminodiphenyl methane and trimellitic anhydride.
