Abstract

The properties of shaped articles (such as films, fibres, tubes, or rods) manufactured by the use of heat and pressure from polyvinyl chloride, interpolymers of vinyl chloride and other compounds polymerizable under the same conditions (such as styrene, acrylic nitrile, acrylic or methacrylic esters), or conversion products of the said polymerization products (such as chlorinated products) are improved by heating them, without pressure, to temperatures, above those used in the manufacture, at which the articles have practically no elastic extension and only small tensile strength, but which temperatures are below their decomposition points. Suitable temperatures lie between 220 and 320 DEG C. The products may subsequently be stretched at a lower temperature.
