1,205,423. Polymer compositions. UNIROYAL Inc. 28 Nov., 1967 [6 Dec., 1966; 1 Nov., 1967], No. 53980/67. Heading C3P. Dye receptive fibre-forming compositions comprise (A) 90 to 97 weight per cent of a polyalkene-1; (B) 0.5 to 5 weight per cent of a thermoplastic nitrogen-containing polymer having a basic ionization constant greater than 1 x 10-14 and which is (a) an intralinear waterinsoluble condensation polyamide or (b) a water-insoluble polymer containing aliphatic, aromatic or heterocyclic amino groups; and (c) 0.5 to 5 weight per cent of an hydrophilic ethylene oxide polymer of molecular weight 300 to 1500 or 100,000 to 7,000,000, a degree of polymerization of at least 4 and an ethylene oxide content of at least 60 weight per cent, which is an ethylene oxide homopolymer or ether or ester thereof or an ethylene oxide/ alkylene oxide copolymer; the total weight of B + C being at least 3 per cent of the composition. (A) may be a polymer or copolymer of ethylene, propylene, 3 - methylbutene - 1 or 4 - methylpentene - 1. (B) may be a polymer or copolymer of an alkenyl pyridine, alkenyl alkyl pyridine or vinyl quinoline; a polyamide, e.g. polyhexamethylene adipamide, polyhexamethylene sebacamide, polypyrrolidinone, polycaprolactam, polyenantholactam or polyhexamethylene adipamide/sebacamide; or a reaction product of 3 - dimethylaminopropylamine and a styrene/maleic anhydride copolymer or of N-methyl bis (aminopropyl)amine with tolylene diisocyanate. The ethylene oxide polymer may be a polyethylene oxide, random or block ethylene oxide/propylene oxide copolymer, or polyethylene glycol ether or ester, e.g. of alkyl phenols, fatty acids and partial esters of fatty acids and hexitol anhydrides. The compositions may be melt spun into dyeable fibres. Many suitable materials are listed and examples describe compositions comprising polypropylene, poly - 2 - vinylpyridine and (1, 2, 10, 15, 17, 18 and 19) polyethylene glycol, (12) polyethylene glycol monomethyl ether, (13) polyethyleneglycol octylphenyl ether and (14) polyethylene glycol distearate, polyethylene glycol monostearate, polyethylene glycol sorbitan monostearate or polyethylene glycol sorbitan monolaurate; polypropylene, polyethylene glycol and (3 and 5) 2 - vinylpyridine/2 - methyl - 5 - vinylpyridine copolymers, (4) polycaprolactam, polyhexamethylene adipamide or a hexamethylene adipamide/hexamethylene sebacamide/caprolactam copolymer and (8 and 9) styrene/ dimethylaminopropyl maleimide copolymers; and poly - 2 - vinylpyridine, polyethylene glycol and (6) polyethylene and (7) poly-4-methylpentene-1.
