Abstract
A finely-divided polyester, especially a polyethylene terephthalate, is made by dissolving the polyester in a halogenated lower fatty acid or an aqueous solution thereof containing at least 80% of halogenated fatty acid, and precipitating the polyester in finely-divided form by adding to the solution an aqueous solution of a halogenated lower fatty acid containing not more than 50% by weight of the halogenated fatty acid. In the examples, the precipitated polyester is washed with water. The halogenated fatty acid may be di- or trichloroacetic acid, trifluoroacetic acid, dichloropropionic acid or mixtures obtained by chlorinating acetic acid which may contain some free acetic acid. The finely-divided polyester may be used as a moulding powder, or may be incorporated with a pigment, preferably before drying, to provide pigment mixtures suitable for the coloration of polyamides or polyesters (e.g. polyethylene terephthalate) or for the preparation of coating compositions for application to paper or textiles.
