The polymerization of furfuryl alcohol with p-toluenesulfonic acid: photocross-linkeable feature of the polymer

Abstract

Poly(furfuryl alcohol) with different amounts of oxymethylenic bridges was synthesized using trifluoroacetic and p-toluenesulfonic acid. All polymers displayed a tendency to retain acids. The isolated products containing traces of acid became insoluble in a few hours; while neutral material maintains their solubility for at least one month. Polymers stored in solution were stable according to their ¹H NMR spectra. Polymers cross-linked after being exposed to UV radiation. The product of the reaction of polymer with maleic anhydride is useful for preparing negative photoresists

Effects of the Type of Catalyst on the Polymerisation Mechanism of Furfuryl Alcohol and its Resultant Properties

“…These findings confirm the complex nature of the mechanism of furfuryl alcohol polymerisation. Nonetheless, several authors have reported that at early stages of furfuryl alcohol resinification, intermolecular dehydration predominates whereby the active α-hydrogen atom of another monomer attacks the hydroxyl group of one monomer, eliminating water in the process [14,19,[23][24][25]. Kim et al [26] reported that the formation of a conjugated diene structure was preferred over a diketone structure in the acid catalysed furfural alcohol polymerization reaction.…”

Effect of furfuryl alcohol addition on the cure of furfuryl alcohol resin used in the glassy carbon manufacture

“…Nowadays, a common thermoset resin used for the glassy carbon production is the phenolic one 10–18. However, the use of furfuryl alcohol resin has presentedsome advantages in the glassy carbon manufacture because it shows more controlled cure kinetics and a lower gel temperature (∼ 60°C) 19–24. The synthesis route of this resin is based on the acid catalysis of furfuryl alcohol and the reaction mechanism of this reaction was suggested by Dunlop and Peters 24.…”

Study by thermal analysis of composites prepared from silica gel, furfuryl alcohol and acetaldehyde

“…Part of it is likely to be involved in the protonation of vinyl bonds of the polyconjugated chains responsible for the color of the resin11 and in ester formation. This phenomenon was previously observed in the polymerization of alkenylfurans17, 18 and FA in solution 19…”
