    Abstract: PURPOSE:To improve the dispersibility of an inorganic filler in the obtained polyurethane resin by introducing carboxyl groups thereinto and increases its adhesion to metals, etc., by performing a urethane formation reaction by using a specified lactone polyester polyol, an organic diisocyanate and optionally a short-chain diol. CONSTITUTION:A lactone polyester polyol (A) obtained by addition-polymerizing, by ring opening, a lactone by using a dihydroxycarboxylic acid as an initiator is reacted with an organic diisocyanate (B) and optionally a short-chain diol (C) to obtain a polyurethane resin of a carboxyl group concentration >=0.09meq/g. By using the dihydroxycarboxylic acid as an initiator in the synthesis of component A, one carboxyl group can be exactly introduced into one polycaprolactone polyol and the carboxyl group content in the polyurethane can be freely controlled.

    Abstract: PURPOSE:A specific lactone-modified polyamide diol is used as a polyol compo nent and combined with an organic diisocyanate and a chain extender to give a polyurethane which is useful as paint and other products, because it has high heat resistance, flexibility, water resistance and dispersion. CONSTITUTION:The objective polyurethane is obtained by admixing (A) a lactone-modified amide diol as the diol component, which is prepared by ring- opening polymerization of (i) a 5-97pts.wt. of a lactone onto that amino groups in 95-3pts.wt. of a diamine polyamide resulting from the reaction between (i) at least one selected from polyamide-forming compounds such as 6-12C aminocarboxylic acids or their lactams or nylons salts of 4-12C dicarboxylic acids and 4-12C diamines, and (ii) a 2-12C diamine (e.g., n+m=13 in the formula), (B) an organic diisocyanate and (C) a chain extender such as 1,4- butanediol.

    Abstract: PURPOSE: To obtain a lactone-modified compound, by reacting an alcoholic hydroxyl group-free acyclic ester compound having a specified structure in the molecule with ε-caprolactone and an initiator for lactone ring opening in the presence of a catalyst without being accompanied with condensation.
    CONSTITUTION: The titled compound is obtained by reacting an aliphatic hydroxyl group-free acyclic ester compound having at least one structure of the formula in the molecule (e.g., an ester of a monobasic aliphatic carboxylic acid with a monohydric alcohol, such as methyl formate) with ε-caprolactone and an initiator for lactone ring opening (e.g., water or an alcohol in an amount of, preferably, 0.01W5wt%, based on the total amount of the ester compound and ε-carprolactone) in the presence of a catalyst (e.g., an organotitanium compound in an amount of several W 100ppm) without being accompanied by condensation.
