0.1 equivalent of an acid polyester obtained from 11 mols of adipic acid and 10 mols of hexanediol (equivalent weight=1,080), 0.1 equivalent of a branched acid polyester obtained from 17 mols of succinic acid, 14 mols of butane-1,4-diol and 1 mol of glycerol (equivalent weight=1,460) and 0.2 equivalent of a hexahydrophthalic acid diglycidyl ester with an epoxide equivalent weight of 160 are warmed and mixed well. After adding 0.3%=0.9 g of 1-methylimidazole, the mixture is evacuated and poured into aluminium tubes. After heating to 140° for 16 hours, crystalline, crosslinked mouldings with the following characteristics are obtained:
