Title
(EN) HYBRID POLYURETHANE-POLYHYDROXYURETHANE COMPOSITION
(FR) COMPOSITION HYBRIDE DE POLYURÉTHANE-POLYHYDROXYURÉTHANE
Abstract
(EN)
The present invention relates to a hybrid polyurethane-polyhydroxyurethane (PU-PHU) composition obtained by a process comprising the following steps: (i) Reacting at least one isocyanate containing compound, in stoichiometric excess, with at least one isocyanate-reactive compound, resulting in the formation of at least one prepolymer, (ii) Reacting said at least one prepolymer with at least one cyclic carbonate functional group containing compound, leading to the formation of a cyclic carbonate-terminated prepolymer, (iii) Ring-opening reaction of said cyclic carbonate-terminated prepolymer with at least one amine functional group containing compound resulting in said hybrid PU-PHU composition, characterised in that said ring-opening reaction step is carried out above room temperature, preferably above 20°C, more preferably above 25°C.
(FR)
La présente invention concerne une composition hybride de polyuréthane-polyhydroxyuréthane (PU-PHU) obtenue par un procédé comprenant les étapes suivantes consistant à : (i) faire réagir au moins un composé contenant un isocyanate, en excès stœchiométrique, avec au moins un composé réagissant avec un isocyanate, conduisant ainsi à la formation d'au moins un prépolymère, (ii) faire réagir ledit au moins un prépolymère avec au moins un composé contenant un groupe fonctionnel carbonate cyclique, conduisant à la formation d'un prépolymère à terminaison carbonate cyclique, (iii) réaliser une réaction d'ouverture de cycle dudit prépolymère à terminaison carbonate cyclique avec au moins un composé contenant un groupe fonctionnel amine conduisant à ladite composition hybride de PU-PHU, caractérisé en ce que ladite étape de réaction d'ouverture de cycle est réalisée à une température supérieure à la température ambiante, de préférence supérieure à 20 °C, de préférence encore supérieure à 25 °C.
