Title:
POLYESTER POLYOL
Document Type and Number:
WIPO Patent Application WO/2008/029527
Kind Code:
A1
Abstract:
A star-branched polyester polyol can be produced by polymerizing lactide or lactic
acid using, as an initiator, an oil-and-fat composed mainly of a triacylglycerol having
at least three hydroxyl or epoxy groups in the molecule. The polyester polyol
shows good working properties in various applications because of its low crystallinity
and low melting point. The polyester polyol is derived from a recyclable resource
and therefore is effective for global environmental conservation and fossil
resource depletion resolution. Thus, the polyester polyol is quite excellent.
