Abstract
Linear polyamides are formed from oxalic acid and a di-methyl hexamethylene diamine or a mixture of two diamines at least one of which is mono-methyl hexamethylene diamine. In the substituted hexamethylene diamines the methyl groups are in 2, 3, 4 or 5 position. Minor amounts of conventional diamines, dibasic acids, monoaminomonocarboxylic acids or caprolactam may be included in the reaction mixture. Ingredients may be present as amideforming ingredients, e.g. as oxamic esters of the diamines or as diamine-dibasic acid salts. Monofunctional amide forming ingredients may be included as described in Specification 495,790, [Group IV]. Preferably lower alkyl or aryl esters of oxalic acid are used and mixed with the diamine in the cold preferably with a solvent. When the initial reaction ceases, heat is applied to drive off solvent and alcohol formed in the reaction. Final heating may be at 300 DEG C. under reduced pressure. Conventional reaction techniques may be employed. Examples are given employing (1) 3,4-dimethyl hexamethylene diamine; (2) a mixture of 3-methyl-hexamethylene diamine with hexamethylene diamine; and (3) a mixture of 2-methyl and 3-methyl hexamethylene diamine. Physical properties of fibres spun from the polymers are given.
