Abstract

A finely-divided, inert, inorganic or organic substance or mixture of substances is incorporated with highly polymeric linear esters obtainable by heating glycols of the series HO(CH2)nOH, where n is greater than 1 and not greater than 10, with terephthalic acid or an ester-forming derivative of the acid by adding the substance or mixture of substances in the form of a dispersion in a glycol of the series HO(CH2)nOH, where n is an integer greater than 1 but not exceeding 10, preferably the glycol used in the polyester formation, to the mixture of polyester-forming reactants or to a low molecular weight product thereof and continuing the reaction to yield a highly polymerized product. The substances added may be titanium dioxide, zinc sulphide, barium titanate, barium sulphate, calcium sulphate extended with titanium dioxide, zinc titanate, magnesium titanate, calcium titanate, lithopone, zirconium dioxide, calcium sulphate, aluminium oxide, thorium oxide, talc, mica, kaolin, carbon black, phthalocyanine pigments, lead chromates, iron oxides, chromium oxides and ultramarine, and the particle size is not larger than 25 microns and preferably less than 5 microns. The substances are added in the form of a suspension formed by ball milling the inert filler in the glycol. Ten parts titanium dioxide are ball milled for three days with 115 parts of ethylene glycol, thus obtaining a dispersion of particle size 0.3-1.3 microns. The dispersion is mixed with dimethyl terephthalate, ethylene glycol and magnesium oxide in a closed flask heated to 197 DEG C. while circulating nitrogen therethrough and taking of methanol. The temperature is increased to 277 DEG C. under pressure of 0.3 mm. glycol, being distilled off and a melt obtained which can be extruded into fibres.
