Title:
POLYCARBONATE DIOL, PROCESS FOR PRODUCING SAME, AND POLYURETHANE AND ACTINIC-ENERGY-RAY-CURABLE POLYMER COMPOSITION BOTH FORMED USING SAME
Document Type and Number:
WIPO Patent Application WO/2011/129377
Kind Code:
A1
Abstract:
Provided is a novel polycarbonate diol giving a polycarbonate polyurethane which has high hardness and excellent mar resistance, has excellent hydrophilicity, and is useful for applications such as paints, coating compositions, synthetic/artificial leathers, and high-performance elastomers, etc. Also provided are: a polyurethane which is formed using the polycarbonate diol as a starting material; and an actinic-energy-ray-curable polymer composition which gives a cured film having excellent stain resistance and hardness. The polycarbonate diol is obtained, for example, by reacting two specific diols with a carbonic acid diester in the presence of a transesterification catalyst which is a compound containing a Group-1 or Group-2 metal of the periodic table, the content of the metal of the transesterification catalyst in the polycarbonate diol being 100 weight ppm or less. The polyurethane is obtained using the polycarbonate diol. The actinic-energy-ray-curable polymer composition contains a urethane (meth)acrylate oligomer which is a product of reaction of the polycarbonate diol.
