DIAMIDO ALKOXIDES AS POLYMERISATION INITIATORS

摘要

The present invention relates to a complex having the formula (I) wherein M is selected from Sn(II), Sn(IV), Al(III) and Mg(II); each of R<1> and R<2> is independently hydrocarbyl; R<3> is H or hydrocarbyl; and X is a linker group. A further aspect of the invention relates to the use of said complex as a polymerisation initiator, particularly in the polymerisation of lactides.
