LIQUID CARBOXY-CONTAINING POLYESTER OLIGOMER, WATER-COMPATIBLE POLYURETHANE RESIN, AND PROCESS FOR PRODUCING THE SAME |
摘要 |
A carboxy-containing polyester polyol which is obtained by polymerizing epsilon-caprolactone by ring-opening polymerization with a compound represented by the formula (1): HOCH2C(COOH)RCH 2OH (1) (wherein R is C2 or higher alkyl) and which has a number-average molecular weight of 550 to 950 and is liquid at ordinary temperature. This polyol can give a water-compatible polyurethane resin which is excellent in the preservation of a working atmosphere during handling and application and has excellent drying properties after application, and which has homogeneity and excellent stability and is useful in a wide range of applications such as a binder for coating materials, printing inks, etc. and an adhesive. By the production process, a water-compatible polyurethane resin which is excellent in the preservation of a working atmosphere and drying property and is homogeneous and stable can be easily produced.
