Shaped aromatic imide polymer article and method of producing same.

摘要

A shaped aromatic imide polymer article having an excellent mechanical strength, heat resistance, and dimensional stability is produced from aromatic imide polymer particles having a size of 0.5 to 100 mu m and consisting essentially of a polymerization-imidization product of a tetracarboxylic acid component comprising 80 molar% or more of a biphenyltetracarboxylic dianhydride with a diamine component comprising 50 molar% or more of a phenylene diamine, by a powder compression molding procedure at a temperature of 200 DEG C to 600 DEG C and under a compression pressure of 300 to 10,000 kg/cm<2>.
