Abstract

Procédé de production d'un polyuréthanne possédant une densité de l'ordre de 0,3 à 0,7 g/cc ainsi que de bonnes propriétés physiques et dynamiques, consistant à préchauffer un prépolymère consistant en un di-isocyanate de 4,4'-diphénylméthane et un polyol polymère possédant un poids moléculaire d'au moins 1000, puis à mélanger ce prépolymère avec un mélange résineux d'un polyol polymère qui peut être le même que le premier polyol.
