Abstract

A solution of a sulphochlorinated polyolefine is spun into a primary or secondary diamine or into a solution of a primary or a secondary diamine in a solvent which is miscible with the solvent of the spinning solution. The polyolefine may be polyethylene, polypropylene, or an ethylene/propylene copolymer. The polymer solvent may be an aromatic hydrocarbon, a light petroleum spirit, or a halogenated hydrocarbon such as chlorobenzene chloroform or carbon tetrachloride. The last-named solvent is especially advantageous since the polyolefine is dissolved therein for sulphochlorination. The diamines (which cross-link the sulphochlorinated polyolefines) may be primary or secondary aliphatic, aromatic or araliphatic diamines, aliphatic diamines being used with special advantage. The carbon chain of the diamines may also be interrupted by bridging elements or groups such as oxygen or the carbonyl group. The amines which may be used include phenylenediamines, 4,41-diaminobenzophenone, xylylene diamine, the diaminodecanes, 2,21-diamino-diethyl ether, and N,N1-dimethyl-ethylene-diamine. Diamines having a chain of 2 to 6 carbon atoms are used with special advantage. In the preferred wet spinning process, the diamine solvent used for the coagulating bath may be a monohydric short-chain alcohol and/or a low molecular weight ketone. The coagulating bath may contain a compound such as a tertiary amine or sodium bicarbonate to neutralize the hydrochloric acid formed by the reaction between the sulphochlorinated polyolefine and the diamine which takes place in the bath. The filaments formed in the bath may be washed by passing them through a bath of hot water and stretched.
