Abstract:
The present invention relates to the field of polymerisation catalysts, and systems comprising these catalysts for polymerising carbon dioxide and an epoxide, a lactide and/or lactone, and/or an epoxide and an anhydride. The catalyst is of formula (I): wherein at least one of M 1  or M 2  is selected from Ni(II) and Ni(III)-X. A process for the reaction of carbon dioxide with an epoxide; an epoxide and an anhydride; and/or a lactide and/or a lactone in the presence of the catalyst is also described.

Claim (Index 3):
The catalyst of  claim 1 , wherein one of M 1  or M 2  is selected from Ni(II) and Ni(III)-X and the remaining occurrence of M 1  and M 2  is selected from Zn(II), Cr(III)-X, Cr(II), Co(III)-X, Co(II), Cu(II), Mn(III)-X, Mn(II), Mg(II), Ni(II), Ni(III)-X, Fe(II), Fe(III)-X, Ti(II), Ti(III)-X, V(II), V(III)-X, Ge(IV)-(X) 2  and Ti(IV)-(X) 2 .
