Title (EN) SELECTIVE CHEMICAL REACTIONS AND POLYMERS OF CONTROLLED ARCHITECTURE PRODUCED THEREBY
(FR) REACTIONS CHIMIQUES SELECTIVES ET POLYMERES A STRUCTURE REGULEE AINSI OBTENUS
Abstract:
(EN) A process for the preparation of a compound or polymer having at least one functional group selected from hydroxyl, thiol, amino and carboxylic acid groups is characterized in that a compound or polymer (A) containing a group of formula (I), where Q represents O or S and X represents -O-, -S-, -NH- or a direct bond, the group being linked to the remainder of the compound or polymer through a carbon atom, is reacted with a compound (B) containing at least two functional groups selected from hydroxyl, thiol, amino and carboxylic acid groups, one of which functional groups (II) reacts with the group of formula (I) and one of which functional grops (III) is substantially unreactive with the group of formula (I) under the conditions of reaction, so that the compound (B) becomes bonded to (A) through the reaction of groups (I) and (II) forming a compound or polymer containing unreacted functional groups (III). The invention also includes dendritic polymers obtainable by the process and intermediates obtainable in the process.
(FR) Procédé de préparation d'un composé ou polymère possédant au moins un groupe fonctionnel sélectionné parmi des groupes hydroxyle, thiol, amino et acide carboxylique. Ce procédé se caractérise en ce qu'un composé ou polymère (A) renfermant un groupe de la formule (I) dans laquelle Q représente O ou S et X représente -O-, -S-, -NH- ou une liaison directe, le groupe étant lié au reste du composé ou polymère par un atome de carbone, est mis à réagir avec un composé (B) contenant au moins deux groupes fonctionnels sélectionnés parmi des groupes hydroxyle, thiol, amino et acide carboxylique, l'un de ces groupes fonctionnels (II) réagissant avec le groupe de la formule (I) et un autre de ces groupes fonctionnels (III) n'ayant pratiquement pas de réaction avec le groupe de la formule (I) dans les conditions de réaction, de sorte que le composé (B) se lie à (A) par la réaction des groupes (I) et (II) formant un composé ou polymère contenant des groupes fonctionnels (III) n'ayant pas réagi. L'invention se rapporte également à des polymères ainsi qu'à des intermédiaires pouvant être obtenus par ce procédé.
