Title (EN) POLYISOCYANATE PREPOLYMERS PREPARED FROM RIGID POLYAROMATIC PRECURSOR MATERIALS, AND POLYURETHANES PREPARED THEREFROM
(FR) PREPOLYMERES DE POLYISOCYANATE PREPARES A PARTIR DE MATERIAUX PRECURSEURS POLYAROMATIQUES RIGIDES, ET POLYURETHANES PREPARES A PARTIR DE CES PREPOLYMERES
Abstract:
(EN) This invention relates to a liquid prepolymer composition which contains free isocyanate groups and which is the reaction product of a stoichiometric excess of a polyisocyanate and an active hydrogen-containing compound which contains an internal rigid polyaromatic grouping. This invention also relates to polyurethane and/or polyurea polymers made from these prepolymer compositions.
(FR) Cette invention concerne une composition prépolymère liquide qui contient des groupes d'isocyanate libres et qui est le produit de réaction d'une quantité stoïchiométrique excessive d'un polyisocyanate et d'un composé contenant de l'hydrogène actif qui contient un groupement polyaromatique interne rigide. Cette invention concerne également des polymères de polyuréthane et/ou de polyurée obtenus à partir de ces compositions prépolymères.
