2.1.5.1.2 Living Ring-Opening Metathesis Polymerization of Copolymers

DOI: 10.1055/sos-SD-224-00037

Due to the living nature of ring-opening metathesis polymerization (ROMP), block copolymers with narrow molar-mass distributions can be easily prepared by simply adding a second monomer to the reaction solution after complete consumption of the first monomer. Statistical copolymers can be prepared by mixing the monomers prior to addition of the catalyst. Different norbornene derivatives are often used, and extensive literature exists for the synthesis of various norbornene derivatives.[‌4‌,‌5‌,‌7‌,‌21‌,‌52‌] Scheme 6 lists examples of block copolymers synthesized via ROMP.
