POLYLACTIC ACID-BASED POLYOL COMPOSITION, PROCESS FOR PRODUCTION THEREOF, URETHANE RESIN COMPOSITION, PROCESS FOR PRODUCTION OF SAME, AND MOLDED PRODUCTS THEREOF |
摘要 |
<p>Provided is a polylactic acid-based polyol composition in which a catalyst that remains in the polylactic acid-based polyol and that acts also as a catalyst for urethane formation has been deactivated by easy means. Thus, the polylactic acid-based polyol composition suffers from little influence of the catalyst on urethane formation. When the polylactic acid-based polyol composition is used as a raw material for a urethane resin, therefore, uniform molded products can be obtained. Also provided are a process for the production of the polylactic acid-based polyol composition, a urethane resin composition obtained using the polylactic acid-based polyol composition, a process for the production of the same, and molded products thereof. The polylactic acid-based polyol composition is a composition which comprises both a polylactic acid-based polyol prepared by transesterification and a silica compound and in which the silica compound has a surface area of 40m2 or more per 100g of the polylactic acid-based polyol and the content of the silica compound is 70% by mass or less.</p> |
