Abstract
Provided is an aromatic polysulfone resin composition comprising 100 parts by weight of an aromatic polysulfone resin compounded with 5 to 240 parts by weight of glass fiber whose surface is treated with an urethane resin. The aromatic polysulfone resin composition is extremely useful as a material for heat-resistant usage including electronic and electric parts because of excellent heat resistance, excellent mechanical properties, high heat stability during mold-procession and low level of gas occluded in the resulting molded article.
