Abstract
Polyacrylonitrile threads containing basic groups and at least 85 per cent by weight of polyacrylonitrile are formed by extruding a solution of the polymer in a concentrated solution of a thiocyanate into an aqueous coagulating bath, and their heat and alkali stability are then improved by treating them before drying with one or more aqueous solutions containing polymetaphosphate ions and orthophosphate ions. A solution containing 1-15 per cent of orthophosphoric acid and 0.2-5 per cent of sodium hexa-meta-phosphate may be used. Copolymers of acrylonitrile with basic compounds, e.g. acrylonitrile-quaternized ammonium salt copolymers formed from an acrylonitrile-vinyl pyridine copolymer in which the vinyl pyridine has been quaternized either in the polymer before spinning or in the extruded thread, blends or copolymers of acrylonitrile with other polymeric compounds containing basic groups, e.g. blends of acrylonitrile with casein, with a vinyl pyridine that has been quaternized or with an acrylonitrilevinyl pyridine copolymer that has been quaternized, quaternized copolymers prepared by copolymerizing an aryl sulphonic ester of an unsaturated alcohol with acrylonitrile and then reacting with a tertiary amine such as pyridine, or block copolymers of acrylonitrile and a polymer containing basic groups, e.g. polyethyleneimine, may be used. Specifications 459,596, [Group IV], 714,530, 732,135, 744,487 and 796,294 are referred to.
