Title (EN) POLYMERS AND THEIR PREPARATION
(FR) POLYMERES ET PREPARATION DE CES POLYMERES
Abstract:
(EN) Hyperbranched polymers containing linkages selected from urea, urethane, carbonate, ester and amine linkages are described. A hyperbranched polymer is prepared by reacting a polyfunctional compound having three reactive functional groups (B) in substantially equimolar quantities with a reagent which reacts rapidly with group (B) to form a group (A) which reacts more slowly with group (B), or by the polymerisation of a compound containing a single group (A) of one chemical type and at least two groups (B) of a different chemical type which is reactive with (A), either (A) or (B) being a group of formula (I) where Q represents O or S and X represents -O-, -S-, -NH- or a direct bond.
(FR) L'invention concerne des polymères hyperramifiés contenant des liaisons sélectionnées parmi les liaisons urée, uréthane, carbonate, ester et amine. La préparation d'un polymère hyperramifié consiste à faire réagir un composé polyfonctionnel contenant trois groupes fonctionnels réactifs (B), présents en quantités sensiblement équimolaires, avec un réactif qui réagit rapidement avec le groupe (B) et ce, dans le but de former un groupe (A) qui réagit plus lentement avec le groupe (B); ou à polymériser un composé contenant un groupe unique (A) d'un type chimique et au moins deux groupes (B) d'un type chimique différent réagissant avec (A). Un groupe de la formule (I) est représenté soit par (A) soit par (B). Dans cette formule Q représente O ou S et X représente -O-, -S-, -NH- ou une liaison directe.
