Abstract

PURPOSE: A urethane resin for civil engineering and architcture use having improved weather resistance and durability and prepared by mixing a urethane resin with the resin prepared by reacting a phenol with a ketone in the presence of an acid catalyst and removing the low-molecular weight compounds from the reaction product.
CONSTITUTION: The composition is prepared by including in a urethane resin composition 1W20wt% of the resin obtained by reacting a phenol represented by formula I, wherein R1 is H or 1W4C alkyl, with a ketone represented by formula II, wherein R2 is 1W4C alkyl, in the presence of an acid catalyst, and removing the low-molecular weight compounds from the reaction product. As the phenol or an alkylphenol is used, and when the latter is used, o- or m-substitution compound is preferred. As the ketone represented by formula II acetone, methyl ethyl ketone or the like is used.
