The synthesis and polymerizability of imine CN monomers is surveyed. The investigated imines were either far more reactive than similarly substituted CC or CO monomers, or too stable to polymerize. Imines with electron-attracting substituents on N fa

The LCP (Liquid Crystal Polymer) known as Vectra is synthesized by acidolysis of 4-hydroxybenzoic acid with 6-hydroxy-2-naphthoic acid. The apparently simple acidolysis mechanism for LCP polycondensation is in fact a complex blend of mechanisms. Kine

In spontaneous vinyl and ring-opening copolymer- izations, polar and resonance effects on the intermediates from bond- forming initiation offer a continu- ous spectrum of reactivities and polymer structures. In bond-form- ing initiation, an electron-

To obtain polyanilines which are more structurally perfect than those obtainable by the oxidation of anilines, polycondensation procedures were investigated. Model reactions gave extensive information about yields and about the physical properties of

The starting premise of this work was that matrices containing powerfully solvating groups would enhance the quality of MALDI-TOF spectra of condensation polymers. The solvating groups in these matrices would pry the polymer aggregates apart and make

To aid in the detailed characterization of the LCP polymer Vectra A950, 20 alternating dimers and 10 alternating tetrameric model oligomers were synthesized and subjected to detailed MALDI and ESI spectral characterization. The model compounds were s

Anionic polymerization of methyl bicyclobutane-1-carboxylate (MBCB) with tert-butyllithium (t-BuLi)/bis(2,6-di-tert-butylphenoxy)ethylaluminum [EtAl(ODBP)2] in toluene at −78 °C gives transtactic polymers (trans contents > 90%) with high yields, b

The zwitterionic–biradical tetramethylene proposed by Huisgen as the key intermediate in stepwise [2+2] cycloaddition reactions has been shown to be the crucial intermediate in spontaneous vinyl polymerizations as well. Predominantly biradical tetr

Bifunctional vinyl ethers react with electron-poor alkenes to cyclobutanes in good yields. The second CC bond reacted with neither the cyclobutane nor its zwitterion intermediate, even on heating. Cyclobutanes formed from ‘tetracyanoethylene’ (8)

Vectra, a commercial copolymer of 4-hydroxybenzoic acid (HBA) and 6-hydroxy-2-naphthoic acid (HNA), is highly intractable, and its analysis has always been problematic. Lower molecular weight polym...
