Abstract: A polymer composition for the production of shaped objects via selective sintering includes ?70.0 wt % of poly(ethylene terephthalate), wherein ?25.0 wt % and ?90.0 wt % of the poly(ethylene terephthalate has resulted from a selective sintering process as unsintered material. The polymer composition is a powder having a D10 of ?10 and ?40 ?m, a D50 of ?75 and ?100 ?m, and a D90 of ?160 and ?200 ?m. The polymer composition allows for the production of an article having a continuous use temperature of ?100° C., and results in a low change of molecular weight during exposure to selective sintering powder processing temperatures. Further, the polymer composition allows for a significant reduction of the waste material generated during selective sintering as the unsintered material does not have to be disposed of as waste but may be used again.
