Abstract
Ethylene terephthalate polyester compositions having a high melt viscosity but which are spinnable to filaments having a low relative viscosity have dissolved in them a boron compound in such amount that the polyester contains at least 0,5 mol. per cent of boron. Preferably the compositions are made by (a) adding to the polyester precursor 3-20 mol. per cent of a soluble boric acid, organic borate or inorganic borate of formula Xm-1Bq\Op where X is hydrogen or metal having the valence of n, m is 1-7, n is 1-3, p is 1-8 and q is 2-15 and wherein <F\1> and (b) subjecting the composition to polyesterification conditions in the presence of a catalyst (e.g. antimony trioxide, tetraisopropyl titanate or manganous acetate). The polyesterification mixture may also include titanium dioxide and phosphoric acid. The boron compound may also be added to the preformed polyester. Specified boron compounds are boric acid, boric oxide, sodium tetraborate, methyl metaborate, methyl polyborate, triethyl borate, triphenyl borate, glycol borate and glycol metaborate. The polyester is one in which at least 75% of the residues are ethylene terephthalate radicals but it may also contain the residues of another dicarboxylic acid (e.g. adipic, sebacic, isophthalic, 5-(sodium sulpho)-isophthalic, bibenzoic, hexahydroterephthalic, diphenoxyethane-4,41-dicarboxylic or p,p1-sulphonyl bibenzoic acid) or another glycol (e.g. tetramethylene-, hexamethylene-, decamethylene-, 2,2-dimethyl-1:3-propylene-, trans-p-hexahydroxylylene- or diethylene-glycols, or bis-p(b -hydroxyethoxy) benzene, bis-1,4-(b -hydroxyethoxy)-2,5-dichlorobenzene, or bis-[p-(b -hydroxyethoxy) phenyl] difluoromethane. The polyesters may be made into staple fibres having a less tendency to "pill". Thus polyethylene terephthalate containing 2,0% by weight of boric acid may be melt-spun into yarn which is drawn 3,26% in a water bath at 100 DEG C., and then heated in an oven maintained at 100 DEG C. whilst free to relax and finally cut up into 1,5 inch lengths. Specifications 578,079 and 841,230 are referred to.
