    Abstract: A process is proposed for production of low-emission moldings for continuous operating temperatures >50° C. composed of a thermoplastic molding composition comprising A) from 10 to 99.9% by weight of polybutylene terephthalate or a mixture thereof with polyethylene terephthalate and/or polypropylene terephthalate, B) from 0.1 to 50% by weight of at least one terpolymer obtainable from b1) at least one vinylaromatic monomer, b2) at least one C1-C4-alkyl (meth)acrylate or (meth)acrylonitrile, and b3) from 0.1 to 10% by weight, based on the total weight of components b1) to b3), of at least one monomer which comprises an alpha,beta-unsaturated anhydride, and C) from 0 to 60% by weight of other additives, where the total of the percentages by weight of the components (A) to (C) is 100%, via injection molding, which comprises carrying out the injection molding by means of a vented plastifying unit with a cylinder with inlet aperture for the thermoplastic molding composition, with a screw which conveys and plastifies the thermoplastic molding composition within a screw channel, and with one or more vents for discharge of volatile content from the plastified thermoplastic molding composition from the screw channel outward from the vented plastifying unit.
