“…TGA measurements revealed a two‐step thermal decomposition process for poly(dialkyl vinyphosphonate)s (alkyl = methyl, ethyl, iso ‐propyl) 5b, 25, 42. In all cases, the second decomposition step occurs at the same temperature range (460–520 °C).…”

Recent studies have shown that poly(vinylphosphonate)s are readily accessible by rare earth metal-mediated group transfer polymerization (GTP). This article highlights the progress in this new field and advantages of GTP in comparison to classical anionic and radical polymerization approaches. Late lanthanide metallocenes proved to be efficient initiators and highly active catalysts for vinylphosphonate polymerization yielding polymers of precise molecular weight and low polydispersity. Using this method, our group has developed a surface-initiated GTP to prepare poly(vinylphosphonate) brushes. In combination with different ester cleavage strategies, rare earth metal-mediated GTP is an efficient way to create well-defined high-molecular-weight poly(vinylphosphonic acid).

“…The magnitude of the weight loss was proportional to the content of PDEVP in the sample, as previously observed for other copolymers. 38 The inset of Fig. 3a shows the weight loss up to 350 C as a function of the PDEVP content determined by 1 H NMR analysis, as discussed in the Experimental section.…”

“…For the PPO-b -PDEVBP 4d-e, the fi rst weight loss was observed at 250 ° C, which corresponds to the loss of diethyl ester groups of -P(O)(C 2 H5O) 2 via formation of ethylene and phosphonic acid groups. [ 30 ] The degradation of C-P bonds also takes place along with this at similar temperatures. The second weight loss appeared above 400 ° C and is attributed to the PPO and aromatic region of the PDEVBP block ( Figure 3 ).…”

Block copolymers containing poly(phenylene oxide) (PPO) and poly(vinyl benzyl phosphonic acid) segments are synthesized via atom transfer radical polymerization (ATRP). Monofunctional PPO blocks are converted into ATRP active macroinitiators, which are then used to polymerize a diethyl p -vinylbenzyl phosphonate monomer in order to obtain phosphonated block copolymers bearing pendent phosphonic ester groups. Poly(phenylene oxide-b -vinyl benzyl phosphonic ester) block copolymers are hydrolyzed to corresponding acid derivatives to investigate their proton conductivity. The effect of the relative humidity (RH) is investigated. The proton conductivity at 50% RH and one bar of vapor pressure approaches 0.01 S cm − 1 .
