Abstract
(EN)
Provided are: a polyurethane resin having excellent heat resistance and fine adhesiveness with respect to various substrates; and an adhesive composition using said resin. This polyurethane resin contains, as copolymerization components, a polycarbonate polyol (A), an organic diisocyanate (B), and a chain extender (C), wherein 60 mol% or more of a specific structure is included in the polycarbonate polyol (A). The polyurethane resin has a glass transition temperature of not less than 50°C.
(FR)
L'invention concerne : une résine de polyuréthane présentant une excellente résistance à la chaleur et une excellente adhésivité fine par rapport à divers substrats ; et une composition adhésive faisant appel à ladite résine. Cette résine de polyuréthane contient, en tant que constituants de copolymérisation, un polycarbonate polyol (A), un diisocyanate organique (B) et un allongeur de chaîne (C), au moins 60 % en moles d'une structure spécifique étant inclus dans le polycarbonate polyol (A). La résine de polyuréthane présente une température de transition vitreuse supérieure ou égale à 50 °C.
(JA)
