Polymerization of Functionalized Norbornenes Employing Mo(CH-t-Bu)(NAr)(O-t-Bu2) as the Initiator.

摘要

Norbornenes containing esters, cyano, acetate, and related functionalities can be polymerized in a living manner employing Mo(CH-t-Bu)(NAr)(O-t-Bu)2 as the initiator, especially in THF, to give polymers with polydispersities as low as 1.04. Living polymers containing Mo-alkylidene end groups have been characterized by proton NMR methods.
