Abstract:
A process for manufacturing a molded object, comprising:a) preparing a shaped object by molding a formulation of: 35 to 100% by weight of a thermoplastic polyester prepared by copolymerizing a diol which is an alkanediol, an alkenediol or a cycloalkane diol, each of 2 to 12 carbon atoms, and an aliphatic, cycloaliphatic or aromatic dicarboxylic acid, 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 and 0 to 5% by weight of other additives and/or processing agents; and b) treating the molded object for at least 1 hour at a temperature ranging from 180 to 250Â° C., thereby preparing a molded object with improved short-time deflection temperature under load properties.
