… copolymer synthesized by ring??opening metathesis copolymerization of cyclooctene and macrocyclic olefin and its hydrolysis to give carboxyl??telechelic polymer
Abstract A novel cleavable multiblock copolymer was synthesized by ring-opening metathesis polymerization (ROMP) of cyclooctene (COE) and a flexible 27-membered macrocyclic olefin (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 copolymer [Poly ( ...
