摘要	Artificial threads are produced 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 catalyst into a coagulant bath containing sulphur dioxide, the polydiene solution having a concentration of at least 10 per cent by weight, and preferably 20 to 40 per cent. The solvents and coagulant baths may be the same, or those described in Specification 679,040. The viscosity of the polydiene solution may be reduced by passing a stream of ozonized oxygen p through it. Specifications 527,075 and 616,276 also are referred to.
