(57) Abstract: Melting to give a molded article believed to have a novel silicon-based interpenetrating structure (IPN) that cures by a condensation reaction and a hydrosilylation reaction of a composition containing a silsesquioxane ladder polymer. To provide a pre-cured product that can be compression-molded and a method for producing a molded product having an arbitrary shape. SOLUTION: The component comprises a silsesquioxane ladder polymer as a main component, which is cured by a hydrolysis / condensation reaction of an alkoxysilyl group and / or a condensation reaction of a silanol group, a silicon compound having a molecular weight of 1,000 or less, and a hydrosilylation catalyst. A novel pre-cured product composed of a component that is cured by a hydrosilylation reaction, a method for producing a molded product obtained by compression molding the same, and a curing method for subjecting the molded product to post-heat treatment. |
