Scheme 1. Synthesis of the desired polymer 1.
a) tBuOK/tBuOH, paraformaldehyde, DMSO, 76 %; b)triphenylphosphine, Bis(dibenzylideneacetone)palladium(0), toluene, 78 %; c) KOH/H2O, DMSO, 48 %; d) 4, Pd(OAc)2, NEt3, Tri(o-tolyl)phosphine, toluene, 78 %, e) adipoyl chloride, hexane diol, DCM. Quantities of monomer 1 and hexane diol were varied in the polymerization to yield polymer 1 with 1%, 5%, and 10% content of monomer.
