Poly(p-phenylene alkylene)s – A forgotten class of polymers

Abstract: Within the wealth of hydrocarbon polymers, poly(p‐phenylene alkylene)s (“alkarotics”) hold a special position since they have been a long forgotten class of hydrophobic polymers. This is somewhat surprising, since the cornerstones of this polymer family cover extremely broad materials properties and the few known representatives attract attention with very favorable characteristics. In the course of this article, four new representatives of this family are presented. Whereas poly(p‐phenylene octylene) (PPPO; 9… Show more

“…18,19 Unlike the related ring-opening metathesis polymerization (ROMP), which is a chain-growth process driven by the release of ring strain, ADMET is driven by the removal of the ethylene gas generated as a by-product. ADMET chemistry has been used recently in the synthesis of both all-carbon polyolefins [20][21][22] as well as polyethylene-like polymers containing heteroatoms [23][24][25][26][27][28][29] or aromatic rings [30][31][32] in the main chain. ADMET offers an interesting alternative for the incorporation of aliphatic sulfonate esters into the polymer backbone, which are rare in the literature.…”

“…PPEs should be uniquely suited for this purpose because catalytic hydrogenation of their triple bonds should lead to a coiled polymer with only a slightly increased molecular weight. The hydrogenated PPE would be an isomeric polystyrene 60 [39], in which the polymer connection is made through the 1,4-positions of the benzene ring instead of the benzene units substituting a polyethylene chain. The polymer 60 is expected to be coiled and thus better amenable to reliable molecular weight determination by GPC using polystyrene standards.…”

“…22 It is noteworthy that the PPPB produced here has a dramatically different melting behavior than the material that was obtained by Brown and Farthing, 21 for which we do not have a plausible explanation; other than that, these authors may not have produced PPPB.…”
