Abstract

1,148,632. Conjugate polyacrylonitrile fibres. FARBENFABRIKEN BAY A.G. 18 Jan., 1967 [2 Feb., 1966], No. 2670/67. Heading B5B. [Also in Division C3] A conjugate filament consists of two components disposed in side-by-side relationship one component consisting of a homopolymer of acrylonitrile or a copolymer of acrylonitrile with 1 to 10% by weight of a comonomer which does not contain any ionizable groups and the other component consisting of a copolymer of acrylonitrile containing at least 70% by weight acrylonitrile in combination with other polymerizable unsaturated compounds, using 1 to 20% by weight of a copolymerizable hydrazide sulphobetaine of the formula wherein X represents a group A, A-NH- or and A represents an aliphatic, aromatic or araliphatic radical having an unsaturated copolymerizable group, R represents an alkylene radical and R<SP>1</SP> and R<SP>11</SP> which may be the same or different represent C 1 to C 5 -alkyl radicals which together with the nitrogen atom may form a heterocyclic ring system. The unsaturated copolymerizable group of the radical A may be the methacrylic acid group. The copolymer of acrylonitrile may have a relative viscosity (# rel.) within the range 1À7 to 2À7 as measured at 20‹ C. in dimethyl formamide at a concentration of 0À5 g./100 ml. The sulphobetaine content of the copolymer component of the conjugate filaments may be 5 to 10% by weight. The conjugate filaments produced may be stretched, e.g. at a stretch ratio of 4 : 1, and at a temperature of about 100‹ C. They may then be heat-set at a temperature within the range of 70‹ to 150‹ C. The unsaturated hydrazide sulphobetaines used in the examples are In the example the copolymer of which the components of the conjugate filaments are composed are separately dissolved in dimethyl formamide and the resulting spinning solutions simultaneously extruded through each extrusion orifice of a spinneret into a gaseous evaporative medium as in normal dry spinning.
