Title (EN) INITIATOR SYSTEM FOR CATIONIC POLYMERIZATION OF OLEFINS
(FR) SYSTÈME INITIATEUR POUR LA POLYMÉRISATION CATIONIQUE D'OLÉFINES
Abstract:
(EN) A Brønsted­Lowry acid initiator system for cationic polymerization of an ethylenically unsaturated monomer involves an initiator having a structure of Formula (I) in an anhydrous polymerization medium (I) where: M is tantalum (Ta), vanadium (V) or niobium (Ni); each R1 is independently H, OR6, F, Cl, Br, I or alkyl, where R6 is H or alkyl; R2, R3, R4 and R5 are independently H, F, Cl, Br, I, alkyl or aryl, or two or more of R2, R3, R4 and R5 on a same benzene ring form a bicyclic, tricyclic or tetracyclic moiety with the benzene ring, with the proviso that all of R2, R3, R4 and R5 on the same benzene ring are not H; L is absent or a molecule that coordinates to H+; and, x is 0 when L is absent, or x is 0.5 or more when L is present.
(FR) La présente invention concerne un système initiateur d'acide de Brønstedlowry pour la polymérisation cationique d'un monomère éthyléniquement insaturé comprenant un initiateur ayant une structure de formule (I) dans un milieu (I) de polymérisation anhydre dans lequel : M est le tantale (Ta), le vanadium (V) ou le niobium (Ni) ; chaque R1 représente indépendamment H, OR6, F, Cl , Br, I ou un alkyle, où R6 représente H ou un alkyle ; R2, R3, R4 et R5 représentent indépendamment H, F, Cl, Br, I, un alkyle ou un aryle, ou deux ou plus de R2, R3, R4 et R5 sur un même noyau benzénique forment une fraction bicyclique, tricyclique ou tétracyclique avec le noyau benzénique, à condition que tous les R2, R3, R4 et R5 sur le même noyau benzénique ne sont pas H ; L est absent ou une molécule qui se coordonne à H+ ; et x est 0 lorsque L est absent, ou x est égal ou supérieur à 0,5 lorsque L est présent.
