Post-functionalization of perfluorophenyl ester-functional acyclic diene metathesis polymer

The acyclic diene metathesis (ADMET) polymerization was utilized for the design of the ADMET polymer (M_n = 21,200 g/mol, M_w/M_n = 1.74) with pendant perfluorophenyl ester functionality using Grubbs first generation catalysis overnight in bulk at 80 °C. Next, a wide variety of functional groups, like benzyl, octyl, propargyl, allyl, and furfuryl was quantitatively incorporated to the ADMET polymer backbone through various amines using activated ester substitution reaction. The ADMET polymers studied in this work were characterized using ¹H, ¹³C, and ¹⁹F NMR, GPC and DSC and displayed a monomodal distribution and a rather broad polydispersity index in the range of −1.33 to 1.90.
