Title:
COMPOUND HAVING THERMALLY DISSOCIABLE THIOACETAL SKELETON, PRECURSOR THEREFOR, CURED ARTICLE, AND COMPOSITION FOR PRODUCING THESE
Document Type and Number:
WIPO Patent Application WO/2003/022802
Kind Code:
A1
Abstract:
A compound having a thioacetal skeleton, precursor therefor, cured article, and composition for producing these are provided as thermally dissociable materials, based on the inventor's finding that a thioacetal group thermally dissociates. Use of the thermally dissociable materials enable the cured article to thermally dissociate any time at a temperature lower than the thermal decomposition temperature of the cured article to thereby soften or liquefy it. Hence, a bonded structure can be disassembled in a short time. The thermally dissociable materials are useful as plastic materials having excellent disposability, and are curable materials useful as a sealing material, coating material, adhesive, etc. They are useful, e.g., as a hardener for a curable urethane composition, curable epoxy composition, etc. or as a cured object formed by self−curing.
