Abstract: A high-molecular-weight polyester is to be prepared in such a way that it is possible to very quickly and advantageously obtain even relatively small amounts having a very high molecular weight.This is achieved by preparing a polyester containing proportions of an alkene diol by continuing the polycondensation step until a viscosity number from 5 to 150 cm.sup.3 /g is reached and subsequently subjecting the polyester thus obtained to a treatment with ionizing radiation until the required viscosity number is reached.With the aid of the process of the invention it is possible to obtain high-molecular-weight polyesters having the desired property profile.

Abstract: Crude product substituted 1,3-diols obtained by aldolization and subsequent hydrogenation are treated at elevated temperatures with at least sufficient basic additives to reduce the saponification number to zero. Thereupon, the saponified product is reacted with 5 to 30% water and possibly cooled to 1.degree. to 30.degree. C. The aqueous phase is separated mechanically, and following the separation and addition of 5 to 30% water the organic phase is adjusted to a pH of 8.0 to 10.5. A second aqueous phase is removed and, thereupon, the monovalent alcohol is removed by distillation from the second organic phase. Again the pH value of the second organic phase is set at 8.0 to 10.5 and the 1,3-diol is recovered by fractionation.
