2.1.5.2.1 Acyclic Diene Metathesis Polymerization

DOI: 10.1055/sos-SD-224-00037

Liu, J.; Johnson, J. A.Science of Synthesis: N-Heterocyclic Carbenes in Catalytic Organic Synthesis, (20162117.

Acyclic diene metathesis (ADMET) polymerization is the step-growth polymerization of dienes catalyzed by alkene metathesis catalysts (Scheme 17). Wagener, Bonchella, and Nel published one of the first successful examples of ADMET chemistry detailing the polymerization of deca-1,9-diene to high molecular weight poly(octene) in 1991 using a tungsten catalyst.[‌111‌] Since then, the development of new metathesis catalysts, including Grubbsʼ second-generation catalyst 4, has expanded the scope of dienes compatible with ADMET and has resulted in many different applications of ADMET polymerization, including an alternative route for the synthesis of linear, branched, or functionalized poly(ethene)s, conjugated polymers for electronic or photonic applications, liquid crystalline polymers, polymers for drug delivery or other biological applications, and polymers prepared from renewable feedstocks.[‌5‌,‌112‌‌114‌]
