Cleavable multiblock copolymer synthesized by ring-opening metathesis copolymerization of cyclooctene and macrocyclic olefin and its hydrolysis to give carboxyl-telechelic polymer
A novel cleavablemultiblockcopolymer was synthesized by ring‐opening metathesispolymerization (ROMP) of cyclooctene (COE) and a flexible 27‐membered macrocyclicolefin (MCO), which is acted as the spacer to collect the polymer structure block by block. MCO 2 was prepared via ring‐closing metathesis of the long chain alkyldiene, and then 2 was well‐ conducted ROMP with COE to provide the multiblock
