PRODUCTION OF THERMOSETTING AROMATIC HYDROCARBON RESIN MOLDING

摘要

PURPOSE:To produce continuously a molding of a heat-resistant resin of excellent properties at high production efficiency. CONSTITUTION:An intermediate polycondensate of a thermosetting aromatic hydrocarbon resin obtained by reacting a fused polycyclic aromatic compound component such as naphthalene, tar or pitch together with a di(hydroxymethyl) benzene- or di(halomethyl)benzene-type crosslinking agent under heating in the presence of an acid catalyst is molded and cured in a mold surface-coated with silicon nitride.
