Abstract
1430867 Cross - linked polymer fibres KANEBO KK 16 April 1973 [14 April 1972] 18299/73 Heading B5B [Also in Division C3] Insoluble, infusible fibres are produced by melt-spinning under a non-oxidizing atmosphere a copolymer of molecular weight 4000 to 500,000 of styrene and an olefinically unsaturated compound in which the molar ratio of styrene to the unsaturated compound is from 99 : 1 to 20 : 80, and then cross-linking the fibres. The olefinically unsaturated compound has at least one functional group which is a halogen atom or a haloalkyl, amino, carboxyl, esterified carboxyl, haloformyl, hydroxyl, amido (ineluding sulphonamido and n-methylamido) or nitrile group. The preferred compounds have either the formula or the formula where R<SP>1</SP> is a hydrogen or halogen atom, a C 1 -C 4 alkyl group, a carboxyl or an esterified carboxyl group; R<SP>2</SP> is a hydrogen atom, a C 1 -C 4 alkyl group or phenyl; X is a functional group as defined above; n is 0 or 1 and m is 1, 2 or 3. The cross-linking agent is applied from a solution which contains from 0À5 to 60% by weight. Its exact nature is selected to accord with the nature of the functional group, and lists of suitable types of agent are given for each group. In the examples the comonomers are mixed o- and p-chioromethylstyrene (cross-linked by pyridine, ethylene diamine and hydroxylamine hydrochloride, diethylamine, disodium ethylene glycol, tetrakis (hydroxy methyl) phosphonium chloride, sodium oxalate, sodium sulphide and hexamethylene diamine), acrylamide (crosslinked by formaldehyde and oxalic acid), paminomethyl styrene (cross-linked by ethylene dibromide, formaldehyde, tolylene diisocyanate and terephthalic acid dichloride), methacrylic acid (ethylene glycol bisglycidyl ether, ethylene dibromide and ethylene diamine), p-hydroxymethyl styrene (xylylene diisocyanate, adipic acid dichloride), allyl alcohol (diphenylmethane diisocyanate), acrylic acid chloride (ethylene diamine, disodium ethylene glycol), methyl methacrylate (disodium ethylene glycol and ethylene diamine), vinyl chloride (ethylene diamine) and vinylidene chloride (ethylene dithioglycol). After spinning the polymer is drawn, if required, then cross-linked, by immersion in a bath of the appropriate reagent, which bath may optionally contain a swelling agent.
