Abstract
The aromatic polysulfone resin composition of the present invention can be produced by mixing 100 parts by weight of an aromatic polysulfone resin and 0.1 to 5 parts by weight of a hydrotalcites and/or a zeolite. Molded articles formed of said composition have a mechanical strength and heat resistance inherent to its constituent resin, and generate low-boiling gases and corrosive gases very little. Therefore, the composition of the present invention is best suited for relay parts.
