Abstract: A process for preparing a filler-fortified polyalkyleneterphthalate molding composition which comprises mixing a filler with a precondensate of poly-(1,4-butylene)-terephthalate and/or poly-(1,3-propylene)-terephthalate, forming the resultant mixture into a shape and thereafter polymerizing the precondensate by solid-phase condensation under solid-phase condensation conditions; a molding composition prepared by such a process comprising poly-(1,4-butylene)-terephthalate and/or poly-(1,3-propylene)-terephthalate in an amount of 20 to 98 weight percent and 2 to 80 weight percent of a fortifying filler, the amounts based upon the combined amount of polyester and fortifying filler; a shaped object prepared from molding such a molding composition and the process for molding such a molding composition into a molded shaped article.
