ABSTRACT:
This invention relates to the controlled molecular weight production of macromonomers and polymers with terminal conjugated double bonds from starting monomers including, but not limited to substituted butadienes. The terminal diene end thus produced is also a potential reaction site for further polymerization or functionalization. The molecular weight is controlled by use of Co chain transfer catalysts and appropriate process conditions.
