Abstract

Fibre-forming linear polycarbonamides are characterized by recurring carbonamide linkages as an integral part of the polymer chain and containing as a component part of the polymer chain between 0.1 and 2.0 mole percentage based on the weight of the polycarbonamide of chain terminal units of the structure: <FORM:1085666/C3/1> wherein n is 0 or an integer from 1 to 6, Z is <FORM:1085666/C3/2> , X is hydrogen or alkyl of 1 to 6 carbon atoms and M is hydrogen, the ammonium radical or an alkali metal. They may be prepared by polymerizing a polycarbonamideforming composition selected from (A) substantially equimolecular proportions of a dibasic acid of the formula HOOC-R-COOH and a diamine of the formula <FORM:1085666/C3/3> and (B) a monoaminomonocarboxylic acid having the formula <FORM:1085666/C3/4> and (C) polycarbonamide forming derivatives of (A) and (B) wherein R is a divalent hydrocarbon radical and X is hydrogen or alkyl of 1 to 6 carbon atoms, in the presence of between 0.1 and 2.0 mole per cent based on the weight of the polycarbonamide of a monofunctional disulphonated compound of the formula <FORM:1085666/C3/5> where n and M are as above and Y is -OH, -Cl or OR1, R1 being a monovalent hydrocarbon radical such that R1-OH is volatile below the decomposition temperature of the polycarbonamide formed. Many examples of the dibasic acids, diamines, monoaminomonocarboxylic acids and monofunctional disulphonated compounds are listed but the examples describe the preparation of polycarbonamides from (a) di(potassium sulphonate)-naphthalene-2-carboxylic acid and hexamethylene diammonium adipate, (b) di(potassium sulphonate)-naphthalene-2-carboxylic acid and epsiloncaprolactam, (c) di(potassium sulphonate)-naphthalene-2-carboxylic acid and hexamethylene diammonium sebacate, (d) di(sulphonic acid) naphthalene-2-carboxylic acid and hexamethylene diammonium adipate and (e) di-(ammonium sulphonate) - naphthalene - 2- carboxylic acid and hexamethylene diammonium adipate.ALSO:Di(potassium sulphonate) - naphthalene - 2 - carboxylic acid may be prepared by reacting 2-naphthoic acid with fuming sulphuric acid followed by slow addition of potassium bicarbonate. The precipitated product so formed may be redissolved in water, treated with activated charcoal and precipitated by the addition of potassium chloride. The corresponding disulphonic acid may be prepared from the potassium salt by passing the salt through a cation-exchange resin. On treating the disulphonic acid with ammonia in aqueous solution, the corresponding ammonium salt is formed.
