  • Polyester polyol
    Patent number: 8058470
    Abstract: A star-branched polyester polyol is obtained by polymerizing lactide or lactic acid, using, as an initiator, a fat and oil composed mainly of a triacylglycerol that has at least three hydroxyl groups or epoxy groups in its molecule. This polyester polyol has low crystallinity and a low melting point, and thus shows good working properties when used in various applications. Furthermore, this polyester polyol is derived from renewable resources, and, thus, it is highly desirable in view of its effectiveness in protecting the global environment and preventing fossil resources from being depleted.
    Type: Grant
    Filed: March 8, 2007
    Date of Patent: November 15, 2011
    Assignees: Bio-Energy Corporation, Osaka University, Kansai Chemical Engineering Co., Ltd.
    Inventors: Hiroshi Uyama, Yinan Yin, Takashi Tsujimoto, Hideo Noda, Takahiko Terada
