POLYCARBONATE DIOL-CONTAINING COMPOSITION, POLYURETHANE USING POLYCARBONATE DIOL-CONTAINING COMPOSITION, AND METHOD FOR PRODUCING POLYCARBONATE DIOL-CONTAINING COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide polycarbonate diol which has good handleability while being a solid at normal temperature, provides polyurethane to which excellent strength, hardness, heat resistance and abrasion resistance are imparted, and enhances processability.;SOLUTION: A polycarbonate diol-containing composition contains polycarbonate diol obtained by a polymerization reaction of diaryl carbonate, diol represented by formula (A) and diol represented by formula (B) in the presence of a metallic compound catalyst, where a glass transition temperature of the polycarbonate diol-containing composition is -20°C or higher. In formula (A), R¹ and R² represent an alkyl group, an aryl group, an alkenyl group, an alkynyl group or an alkoxy group having 1 to 15 carbon atoms, and may have an oxygen atom, a sulfur atom, a nitrogen atom or a halogen atom or a substituent containing them while having 1 to 15 carbon atoms. In formula (B), R³ represents an aliphatic or alicyclic hydrocarbon group which has 1 to 15 carbon atoms and may have a hetero atom.;SELECTED DRAWING: None;COPYRIGHT: (C)2018,JPO&INPIT
