| 摘要 |
Polyolefin articles of improved dyeaffinity are obtained by addition of an ester of an oxyacid of phosphorus or sulphur followed by treatment with an amine which reacts with the ester to form a quaternary ammonium salt. The polyolefin may be derived from ethylene and/or propylene (e.g. isotactic polypropylene), and the specified esters are phosphates, phosphonates, phosphinates, sulphonates and sulphates, in particular methyl bis(p-methoxycarbonyl phenyl) phosphate, methyl toluenep-sulphonate, dimethyl naphthalene 1,5-disulphonate, cetyl methyl sulphate and methyl diphenyl phosphinate. The amines disclosed are trioctylamine, trinonylamine, tridecylamine and cetyldimethylamine. The products may be formed into film, fibre and filaments (which may be drawn), and may be dyed with acid or disperse dyestuffs. Applications specified are carpets, blankets, garments, furs, velvets, furnishing fabrics, knitted articles and non-woven fabrics. Specification 810,023 is referred to.
