Abstract: PURPOSE:To obtain a flexible polyurethane foam with improved air-permeability and organic solvent resistance, useful as sound attenuation material, etc., by the reaction, in the presence of catalyst, foaming agent and foam stabilizer, between a specific polycaprolactone polyol and polyisocyanate. CONSTITUTION:The objective foam can be obtained by the reaction, in the presence of catalyst (e.g., devalent tin salt of fatty acid), foaming agent (e.g., dichloro difluoromethane) and foam stabilizer, between (A) a polycaprolactone polyol with an average hydroxyl value 30-200 and an epsilon-caprolactone residue 5-95wt% and (B) a polyisocyanate (e.g., tolylenediisocyanate, diphenyl-methanediisocyanate). Said polyol will normally be prepared by the reaction, in the presence of catalyst such as tetrabutyl titanate, between polyhydric alcohol such as ethylene glycol, epsilon-caprolactone and, if required, polybasic acid (anhydride) at 140-230 deg.C.

Abstract: PROBLEM TO BE SOLVED: To obtain a polyurethane resin capable of giving a coating surface prevented in blooming and lowering in gloss, by using a lactone polymer containing not more than 0.1 wt.% of a lactone dimer.
SOLUTION: Lactone monomers are polymerized in the presence of a titanium compound as a catalyst. After the formation of a polymer, the reaction mixture is subjected to film distillation to obtain the lactone polymer having not more than 0.1 wt.% of the lactone dimer. Next, the lactone polymer and an isocyanate compound are reacted to obtain a polyurethane resin. A coating material composition is obtained by using the polyurethane resin.

Abstract: PROBLEM TO BE SOLVED: To obtain a polyurethane adhesive having transparency, exhibiting no shrinkage caused by crystallization, scarcely growing molds, useful for adhering and laminating a composite multilayered film, and having excellent adhesion. SOLUTION: This polyurethane adhesive contains a polyurethane which is obtained by reacting a polyester polyol with an organic polyisocyanete as a resin component, wherein the polyester polyol is obtained by polycondensing 2-butyl-2-ethyl-1,3-propanediol (BEPD) with a multivalent carboxylic acid, or polycondensing the BEPD and a polyol other than the BEPD with the multivalent carboxylic acid.

Abstract: PROBLEM TO BE SOLVED: To provide a curable urethane acrylate oligomer which gives a cured coating film excellent in flexibility (low hardness), adherence and hydrolysis resistance, and a photo curable resin composition containing the oligomer. SOLUTION: A urethane prepolymer is obtained by reacting a polyester polyol made of 2-butyl-2-ethyl-1,3-propanediol, or 2-butyl-2-ethyl-1,3-propanediol and a dicarboxylic acid with an organic diisocynate. The urethane prepolymer, serving as one ingredient, is reacted with a hydroxyalkyl(meth)acrylate, serving as other ingredient, to obtain a curable urethane acrylate oligomer. COPYRIGHT: (C)2003,JPO

Abstract: PROBLEM TO BE SOLVED: To improve fabrication property by using composition kneading PET regenerated resin, polyester resin, and optionally the other thermoplastic resin, or additive selected from resin additive and inorganic compound. SOLUTION: With 100 pts.wt. of the crushed substance of PET regenerated resin used for beverage bottle, fiber, film or a large-sized molded object such as a container, 0.5-100 pts.wt. of polyester resin such as poly-caprolactum is combined. With this combined substance, at least one sort of additive (stabilizer, coloring agent, antioxidant, or the like) optionally selected from thermoplastic resin, resin additive, and inorganic compound is mixed in the range not obstructing physical property of the molding, and fused and kneaded by an extruder, Banbury mixer, or the like. This PET regenerated resin composition is molded into an aqueduct meter box by extrusion molding or injection molding. The molding is excellent not only for mechanical property, but for heat resistance and electric insulation.

Abstract: PURPOSE:To produce a lactone-modified diol which can give a urethane resin which by itself can eixibit weathering resistance, by reacting 2,2,6,6- tetramethyl-4-hydroxypiperidine with a lactone. CONSTITUTION:1mol of 2,2,6,6-tetramethyl-4-hydroxypiperidine of formula I is reacted with 2-15mol of a 4-8C lactone to obtain a lactone-modified diol of formula II. When the amount of the lactone added is below 2mol, the flexibility inherent in lactone chains cannot be fully imparted to the formed lactone adduct. When this amount is above 15mol, the MW is excessively large and the viscosity is high, which makes handling in urethane formation difficult. epsilon-Caprolactone is a particularly desirable lactone in many respects.
