Title (EN) METHOD FOR THE PRODUCTION OF A BRANCHED MACROMOLECULE, THE BRANCHED MACROMOLECULE AND USES THEREOF
(FR) PROCEDE SERVANT A PREPARER UNE MACROMOLECULE A CHAINE RAMIFIEE, MACROMOLECULE A CHAINE RAMIFIEE ET SES UTILISATIONS
Abstract:
(EN) The invention relates to a process for the preparation of a branched molecule by: a) reacting a nucleus molecule with a compound of a first type which contains a primary and a tertiary isocyanate group; b) reacting the product so obtained with a compound of a second type which contains a first reactive group which can be reacted with a tertiary isocyanate and one or more groups which react with a primary isocyanate and react with a tertiary isocyanate to a lesser extent than the first reactive group, followed by the alternating performance of the steps (c) and (b), c) reacting the product obtained in step (b) with a compound of the first type. The invention also relates to macromolecules obtainable thereby and to the use thereof.
(FR) L'invention concerne un procédé servant à préparer une molécule à chaîne ramifiée et consistant à (a) effectuer la réaction d'un noyau moléculaire avec un composé de premier type contenant un groupe isocyanate primaire et un groupe isocyanate tertiaire; (b) effectuer la réaction du produit obtenu avec un composé de deuxième type contenant un premier groupe réactif, dont on peut effectuer la réaction avec un isocyanate tertiaire, et un ou plusieurs groupes réagissant avec un isocyanate primaire, ainsi qu'avec un isocyanate tertiaire dans une mesure moindre que le premier groupe réactif, ladite réaction étant suivie par l'exécution alternée des étapes (c) et (b); (c) effectuer la réaction du produit obtenu à l'étape (b) avec un composé de premier type. L'invention concerne également des macromolécules pouvant être obtenues au moyen de ce procédé et leur utilisation.
