Abstract

Chlorinated polyvinyl chloride is worked up by strongly cooling a solution thereof in an organic solvent to form a gel andprecipitating by a non-solvent. A solution of chlorinated polyvinyl chloride, e.g. of 10 per cent strength in tetrachlorethane, may be gelled by cooling to 0-40 DEG C. and a non-solvent, e.g. methanol or other lower aliphatic alcohol or aliphatic hydrocarbons such as petroleum ether or gasoline, added with stirring. Alternatively, a gel obtained in the same way may be extruded, e.g. as a band or fibre, into the preferably pre-cooled non-solvent, which may move in countercurrent or may be situate in more than one bath. Specification 401,200 is referred to.
