Title (EN) METHOD FOR DEBLOCKING A BLOCKED ISOCYANATE AND METHOD OF MAKING A POLYURETHANE
(FR) PROCÉDÉ DE DÉBLOCAGE D'UN ISOCYANATE BLOQUÉ ET PROCÉDÉ DE FABRICATION D'UN POLYURÉTHANE
Abstract:
(EN) A method for deblocking a blocked isocyanate is described herein. The method includes contacting a blocked isocyanate and a halide ion source under conditions effective to provide a deblocked isocyanate. A method of making a polyurethane is also disclosed. The method of making a polyurethane includes combining a blocked isocyanate, a polyol, and a halide ion source in the presence of solvent and under conditions effective to provide the polyurethane.
(FR) La présente invention concerne un procédé de déblocage d'un isocyanate bloqué. Le procédé comprend la mise en contact d'un isocyanate bloqué et d'une source d'ions halogénures dans des conditions efficaces pour fournir un isocyanate débloqué. L'invention concerne également un procédé de fabrication d'un polyuréthane. Le procédé de fabrication d'un polyuréthane comprend la combinaison d'un isocyanate bloqué, d'un polyol et d'une source d'ions halogénures en présence de solvant et dans des conditions efficaces pour fournir le polyuréthane.
