Abstract: The present invention relates to a thermoplastic polyester copolymer comprising 50-1000 ppm with regard to the total weight of the thermoplastic polyester copolymer of moieties derived from an alcohol having ≥3 hydroxy moieties. Such thermoplastic polyester copolymer allows for the production of high-quality foamed articles, whilst reducing the need for additives that are to be incorporated in the copolymer.
