Abstract
(EN)
The present invention provides a polyester polyol which is capable of forming a polyurethane that has excellent durability and excellent solvent resistance. A polyester polyol according to the present invention is represented by formula (1) and has a molecular weight distribution of less than 1.2. In formula (1), R1 and R2 may be the same or different, and each represents a divalent hydrocarbon group; n represents an integer; and R3-R7 may be the same or different, and each represents a hydrogen atom, a monovalent hydrocarbon group or a group represented by formula (2). In formula (2), m and s may be the same or different, and each represents an integer of 1 or more; and 2m-number of R8 moieties may be the same or different, and each represents a hydrogen atom, an alkyl group or an alkoxy group. Incidentally, at least two of the R3-R7 moieties are groups represented by formula (2).
