Abstract

Vinylidene chloride and acrylonitrile are copolymerized in aqueous medium, the initial molar ratio of the monomers being between 3 : 1 and 1 : 3, and the initial water-to-monomer ratio being between 5 : 1 and 10 : 1 by weight, to give an acetone soluble copolymer. Acrylonitrile may be added or vinylidene chloride withdrawn continuously or intermittently during the process. Vinyl chloride may replace part of the vinylidene chloride, 4 to 8 parts of vinyl chloride replacing one part of vinylidene chloride, usually vinylidene chloride or acrylonitrile being added during the process, and/or the process stopped at 30-50 per cent conversion. The terpolymers may be used in the wet or dry spinning of fibres. The polymerization may be carried out continuously in a tube or in a number of vessels in cascade. Substances which may be added are alcohol, hydrocarbons, formaldehyde, acetaldehyde, carbon tetrachloride, dioxane, dodecyl mercaptan, tetra-alkyl-thiuram sulphides and di-sulphides, ammonium or potassium persulphates, water-soluble percarbonates and perborates, hydrogen peroxide, benzoyl, acetyl, acetyl benzoyl, lauryl and the alkyl peroxides, sulphites, bisulphites, hydrosulphites, silver nitrate, copper sulphate, alkali metal ferricyanides and cobalticyanides. The reaction may be stopped by hydroquinone. Using the emulsion technique, sodium sec.-octadecyl sulphate or sodium stearate may be added, while polyvinyl alcohol, bentonite or methyl cellulose may be added when using the suspension technique. The copolymer may be obtained from the latex by freezing, adding an electrolyte, or atomizing into ethanol. Stabilizers such as lead carbonate, naphthenate, laurate or stearate, adipic dihydrazide, oxalic dihydrazide, or phenyl acetamidine may be added to the products, which may be used in mouldings, films or coatings.
