    摘要： The present invention relates to a process for preparing a dispersion of high grade polyester copolymer resin in water comprising 1) combining a crude polyester copolymer resin, having particles of various sizes, with water; 2) heating and agitating the resin/water mixture; 3) cooling the mixture; 4) allowing the mixture to stand undisturbed so that the largest, undispersed particles settle out as a sediment; 5) removing the sediment; and 6) continuously filtering the mixture, using progressively finer filters, leaving only the finest size particles. By using a plurality of filters and sequentially finer filter mesh sizes, a high grade product is attained.
