Abstract
Polymers of substantially uniform average molecular weight are made by polymerizing at least one compound containing a <FORM:0866445/IV (a)/1> group in an aqueous medium at a pH not higher than 4,0 in the presence of a redox catalyst system comprising 0,1% to about 3% by weight of chlorate ions and 0,1% to about 9% by weight of sulphoxy ions and varying the percentage conversion of the polymerizable compound to the polymer by decreasing or decreasing respectively the ratio of molar equivalents of sulphoxy ions to the polymerizable compound together with a decrease or increase respectively in the ratio of molar equivalents of chlorate ions to the polymerizable compound that is greater than the decrease or increase in the ratio or molar equivalents of sulphoxy ions to the polymerizable material. The process may be effected batchwise or continuously. The chlorate ions may be obtained from chloric acid, ammonium, sodium, potassium, or lithium chlorate, or alkaline earth metals or heavy metal chlorates. The sulphoxy ions may be obtained from sulphur dioxide, sulphites, bisulphites, meta-bisulphites, or a water soluble dialkyl sulphite. The Specification contains an extensive list of compounds containing a <FORM:0866445/IV (a)/2> group, e.g. diallyl benzene, styrene, dialkyl styrenes, isopropenyl toluene, acrylonitrile, alkacrylonitriles, substituted acrylamides, vinyl esters, e.g. vinyl acetate, vinyl acrylate, acrylates, methacrylates, diallyl amine, vinyl ethyl ether, vinyl pyridene, and substituted vinyl pyridines. The preferred polymers are copolymers and terpolymers comprising acrylonitrile and a vinyl pyridine which are made into fibres and filaments. Specifications 672,775, 722,451 and 735,225 are referred to.
