Synthesis of stereoblock copolymers via ligand exchange in living stereoselective ring opening metathesis polymerisation of 2,3-bis(trifluoromethyl)bicyclo[2.2.1]hepta-2,5-diene

Abstract

Poly{2,3-bis(trifluoromethyl)bicyclo[2.2.1]hepta-2,5-diene} is synthesised as a stereoblock copolymer containing cis-and trans-vinylene blocks via ligand exchange in living stereoselective ring opening metathesis polymerisation initiated by a well defined Schrock type initiator.
