Title (EN) A POLYMERISATION PROCESS
(FR) PROCÉDÉ DE POLYMÉRISATION
Abstract:
(EN) The present invention relates to a polymerisation process for the reaction of (a) carbon dioxide with an epoxide; and/or (b) an anhydride with an epoxide. The process is carried out in the presence of a chain transfer agent and a catalyst of formula (I): Formula (I) The catalyst comprises groups Y1 and Y2 which are independently a neutral or anionic donor ligand group capable of donating a lone pair to the mental M2. M1 and M2 are independently selected from Zn(ll), Cr(ll), Co(ll), Cu(ll), Mn(ll), Mg(ll), Ni(ll), Fe(ll), Ti(ll), V(ll), Cr(lll), Co(lll), Mn(lll), Ni(lll), Fe(lll), Ca(ll), Ge(ll), Al(lll), Ti(lll), V(lll), Ge(IV), Y(lll), Sc(lll) or Ti(IV). The present invention also relates to a catalyst, and polymers produced by the process using the catalyst and higher polymers such as polyurethanes produced therefrom.
(FR) La présente invention concerne un procédé de polymérisation pour la réaction d’un (a) dioxyde de carbone avec un époxyde ; et/ou (b) d’un anhydride avec un époxyde. Le procédé est mis en œuvre en présence d’un agent de transfert de chaîne et d’un catalyseur de formule (I) : Formule (I) le catalyseur comprend les groupes Y1 et Y2 qui sont indépendamment un groupe ligand donneur neutre ou anionique capable de donner une paire unique au métal M2. M1 et M2 sont indépendamment sélectionnés parmi Zn(II), Cr(II), Co(II), Cu(II), Mn(II), Mg(II), Ni(II), Fe(II), Ti(II), V(II), Cr(III), Co(III), Mn(III), Ni(III), Fe(III), Ca(II), Ge(II), Al(III), Ti(III), V(III), Ge(IV), Y(III), Sc(III) ou Ti(IV). La présente invention concerne également un catalyseur, et les polymères produits par le procédé en utilisant le catalyseur et des polymères supérieurs tels que des polyuréthanes produits à partir de ces derniers.
