Title (EN) CATALYSTS SUITABLE FOR THE RING-OPENING POLYMERISATION OF CYCLIC ESTERS AND CYCLIC AMIDES
(FR) CATALYSEURS APPROPRIÉS POUR LA POLYMÉRISATION PAR OUVERTURE DE CYCLE D'ESTERS CYCLIQUES ET D'AMIDES CYCLIQUES
Abstract:
(EN) A new family of Group IV transition metal catalytic compounds are provided, which are capable of catalysing the ROP of cyclic esters and cyclic amides to yield polymers of high molecular weight and narrow PDI. The new family of catalysts are surprisingly active not only in catalysing the ROP of lactones such as caprolactone, but also macrolactones (e.g. ω-pentadecalactone, PDL), where the reduced amount of ring strain would typically compromise efficient polymerisation. Also provided is a process for the ring opening polymerisation (ROP) of a cyclic ester or a cyclic amide employing the new catalytic compounds.
(FR) L'invention concerne une nouvelle famille de composés catalytiques à métaux de transition du groupe IV capables de catalyser la polymérisation par ouverture de cycle d'esters cycliques et d'amides cycliques pour produire des polymères de poids moléculaire élevé et d'indice de polydispersité (PDI) étroit. La nouvelle famille de catalyseurs est étonnamment active non seulement en catalysant la polymérisation par ouverture de cycle de lactones comme la caprolactone, mais également de macrolactones (par exemple, l'oméga-pentadécalactone, la pentadécanolide), où une quantité réduite de la tension de cycle compromettrait vraisemblablement une polymérisation efficace. L'invention concerne également un procédé pour la polymérisation par ouverture de cycle (ROP) d'un ester cyclique ou d'un amide cyclique employant les nouveaux composés catalytiques.
