Abstract: u A polyester-polyol (I) obtained by subjecting a cyclic ester (II) to ring-opening addition polymerisation with a dihydroxy-carboxylic acid (III) as initiator, in which at least some of the carboxyl groups in (I) are in the form of a carboxylate with a basic compound (IV). Independent claims are included for (1) a method for the production of (I) by ring-opening addition polymerisation of (II) with (III) in presence of (IV) (2) polyurethane resins comprising a polyol component containing (I) and a polyisocyanate component .

Abstract: A method for producing a curing agent for polyurethane coating materials which is composed of an aliphatic diisocyanate or an aliphatic diisocyanate and a polyester polyol is characterized in that a copolymerized lactone polyol is used as the polyester polyol which lactone polyol is obtained through ring-opening copolymerization of at least two kinds of cyclic lactone compounds wherein a low-molecular-weight compound having at least two active hydrogen groups is used as an initiator. By using at least two kinds of cyclic lactone compounds, there can be obtained a curing agent for polyurethane coating materials which enables to form a coating film having high mechanical strength, especially high flexibility and impact resistance at low temperatures, and excellent gloss retention.

Abstract: A polycarbonate polyol composition which can be used to prepare polycarbonate(meth)acrylate and urethane(meth)acrylate compositions is obtained by the ester interchange reaction of a polycarbonate diol composition with a triol and/or tetraol. The (meth)acrylate compositions have excellent photo and electron beam curability and the cured layers prepared therefrom have excellent heat resistance under moisture conditions.

Abstract: Disclosed is a polycarbonatediol composition having a property of liquid under the room temperature because of its crystallinity disordered owing to random structures, which composed of 1,6-hexanediol and polyvalent alcohol having side chain. Accordingly, the disclosed composition has more excellent processability in the case of preparing a polurethane resin etc. And disclosed is a polyurethane resin prepared by reaction of an organic diisocyanate compound with the polycarbonatediol composition. The disclosed polyurethane resin has more excellent properties under the low temperature atomosphere, while retaining high levels of mechanical strength, more excellent resistibility under the heat and moist atomosphere, etc. and thereby maintaining a good balance of properties. The polyurethane resin, which is produced in the present invention, is more useful in a very wide variety of forms including spandex, rigid or flexible urethane foams, thermoplastic urethane elastomers and thermosetting urethane elastomers, adhesives, synthetic leather and paints, etc.
