Abstract

A molded object is manufactured by a process, comprising:a) preparing a shaped object by molding a formulation of:35 to 100% by weight of a thermoplastic polyester,0 to 60% by weight of filler or a reinforcing material,0 to 20% by weight of an impact modifying rubber,0 to 30% by weight of a flame retardant,0 to 20% by weight of a synergist and0 to 5% by weight of other additives and/or processing agents; andb) treating the molded object for at least 1 hour at a temperature ranging from 180 to 250° C., thereby preparing a molded object with improved short-time deflection temperature under load properties.
