摘要:
Novel glycidyl compounds represented by general formula (I): ##STR1## (wherein all the symbols are as defined in the appended claims), and a process for preparation of the glycidyl compounds are disclosed. The glycidyl compounds are prepared by reacting ethersulfonamide represented by general formula (III): ##STR2## (wherein all the symbols are as defined in the appended claims) and epihalohydrin, and then reacting the resultant adduct with an aqueous caustic alkali solution.
摘要:
A novel glycidyl sulfonamide compound having a (poly)siloxane main chain of its molecule is used alone or in admixture with an epoxy resin to give a cured material being excellent in flexibility, elongation and impact strength without deteriorating thermal resistance, chemical resistance and water absorption thereof. An epoxy resin composition or a resin composition for an epoxy paint containing a glycidyl sulfonamide compound, the epoxy resin and a curling agent for epoxy resin provides a cured material or a coating film having the above-mentioned excellent properties. A process for preparing a glycidyl sulfonamide compound characterized in that subjecting an amine modified silicone having a (poly)siloxane main chain of its molecule to condensation reaction with a sulfonyl chloride to give a sulfonamide compound, which is subjected to an addition reaction with an epihalohydrin to give the glycidyl sulfonamide compound.

A method of molding an aromatic polyimide resin, comprising compression molding an aromatic polyimide resin composition powder comprising an aromatic polyimide resin and a fluorine resin added thereto, and then sintering the compression molded product in a mixed gas atmosphere of oxygen and inert gas, having the oxygen concentration of 0.1 to 10% at 360.degree. to 480.degree. C., or sintering the compression molded product in an inert gas atmosphere and then heat treating the same in a mixed gas atmosphere of oxygen and inert gas at 360.degree. to 480.degree. C. This method can solve the problems on color shade and strength due to sintering in the case of molding an aromatic polyimide resin having a fluorine resin added thereto, and can provide a polyimide molding having excellent quality.
摘要:
Herein described is a photovoltaic module (30) that comprises a rectangular module body (61) and a frame (60) secured to the sides of the body. The frame is composed of an upper bar (63), a lower bar (64) and a pair of side bars (65 and 66). The upper bar (63) has an insertion projection (71) projecting from a part which is middle in thickness direction of the upper bar. The projection (71) is thinner than the upper bar (63).
