Abstract

Artificial threads are obtained by extruding a solution of a polydiene such as polybutadiene or polychloroprene or a copolymer of butadiene or chloroprene with styrene or acrylonitrile, containing a hydroperoxide as catalyst into a coagulant bath containing sulphur dioxide wherein the coagulant bath contains at least 5 per cent by weight of the solvent used to dissolve the polydiene. The solvents for the polydiene may be aromatic hydrocarbons such as benzene, toluene, xylene and cumene, and chlorinated hydrocarbons such as trichloroethylene, carbon tetrachloride, chloroform and chlorobenzene. The preferred solvents for the sulphur dioxide are mixtures of the above hydrocarbons with methanol, ethanol, a propanol or acetone. The spinning solution may contain at least 10 per cent of the polydiene as claimed in Specification 679,274, and may contain small proportions of methanol or isopropanol to reduce viscosity and is activated by a hydroperoxide such as tetralin hydroperoxide or tertiary butyl hydroperoxide. Specifications 527,075 and 616,276 also are referred to.
