Abstract: The present invention relates to a molding comprising (i) a poly(butylene dicarboxylate) polyester in an amount in the range of from equal to or greater than 10 to 99.99 weight-%, based on the total weight of the molding, (ii) a zeolitic material in an amount of from 0.01 to 10 weight-%, based on the total weight of the molding, wherein the zeolitic material comprises YO2 and optionally X2O3, wherein Y is a tetravalent element and X is a trivalent element, wherein the zeolitic material has a YO2 to X2O3 molar ratio of higher than 100 if the zeolitic material comprises X2O3. Further, the present invention relates to a process for preparation of such a molding and use thereof.
