Abstract: Polyester moulding materials which can be injection moulded on a technical scale to give products having good mechanical properties are obtained by having present in the polyesterification mixture, besides a terephthalic or mainly terephthalic acid component and a diol component, 0.05-3 moles percent, on the acid component, of a compound containing at least 3, preferably 3 or 4, ester-forming groups this may for example be a tri- or tetra-carboxylic acid, a triol or tetrol, or a hydroxy carboxylic acid containing in all 3 or more ester-forming groups.
