Abstract

L'invention concerne un procédé de préparation d'un composé intermédiaire pour un diisocyanate. Ledit procédé comprend l'étape consistant à faire réagir une diamine de formule H2N-(CH2)0-Y-(CH2)p-NH2, Y étant choisi parmi CH(OX) ou CH(COOX), o et p étant chacun un nombre entier de 0 à 4, à condition que la somme o plus p vaille 4 ou moins, de préférence 2, 3 ou 4, et X étant un groupe protecteur, avec un carbonylbislactame, de préférence un carbonylbiscaprolactame, ladite réaction permettant de former un composé de formule (I) dans laquelle chaque L est un lactame provenant du carbonylbislactame.
