摘要： An object of the present invention is to provide a polyimide porous body having an excellent heat resistance, a fine cell structure, and a low relative dielectric constant, and a method for producing the polyimide porous body. The present invention relates to a method for producing a polyimide porous body, comprising a step for applying a polymer solution containing a polyamide acid, a phase separation agent for separating the phases of the polyamide acid, an imidization catalyst, and a dehydrating agent, on a substrate, and drying the polymer solution to produce a phase-separated structure body having a microphase-separated structure; a step for producing a porous body by removing the phase separation agent from the phase-separated structure body; and a step for subjecting the polyamide acid in the porous body to imidization to synthesize a polyimide.

摘要： The present invention provides a gasket material to be placed between two opposing faces to provide a tight closure between them. The gasket material of the present invention, wherein an adhesive layer comprised of a cured product obtained by reacting a polyoxyalkylene polymer having at least one alkenyl group in each molecule with a compound containing two or more hydrosilyl groups on average in each molecule is formed on both surfaces of a substrate sheet, is superior in elasticity and compaction property, shows superior adhesion to various materials, does not cause cohesive failure during detachment and is superior in removability. Therefore, a superior sealing effect lasts for a long time, the gasket material can be removed without leaving residues of the adhesive layer on an adherend after removal, and workability including removal of the gasket material can be improved.
