Abstract

A catalyst composition comprising a neutral bimetallic diphenoxydiiminate complex of group 10 metals or Ni, Pd or Pt is disclosed. The compositions can be used for the preparation of homo- and co-polymers of olefinic monomer compounds.

Claims

exact text as granted — not AI-modified
1 . A compound of a formula 
       
         
           
           
               
               
           
         
         wherein each R is independently selected from H and an alcohol protecting group; and 
         each R″ is independently selected from alkyl or aryl, and salts thereof. 
       
     
     
         2 . The compound of  claim 1  wherein each R″ is i-propyl. 
     
     
         3 . The compound of  claim 1  comprising a 1,8-naphthalenediolato salt. 
     
     
         4 . The compound of  claim 3  wherein each R″ is i-propyl. 
     
     
         5 . The compound of  claim 4  complexed with a metal species comprising a metal center selected from Ni, Pd and Pt.
