An ACS^[1] Publication describes it as follows: “Poly(furfuryl alcohol) (PFA) is a thermally cross-linked polymer that is synthesized from furfuryl alcohol (FA) derived from renewable saccharidic resources“.

CAS Number: 25212-86-6. Dark, viscous, fluid with double bonds in the polymer backbone. Soluble in: acetone, alcohol, esters, toluene; d²⁵1.36; Viscosity 14,500 “The monomer FA is liquid at room temperature and has high solubility in water and many organic solvents, and its polymerization can be carried out under flexible conditions. Therefore, PFA has been very attractive as a precursor for PFA nanocomposites and carbon materials“.

Some Examples/Applications:

• Novel cellulose ester-poly(furfuryl alcohol)-flax fiber biocomposites
• Molecular sieving platinum nanoparticle catalysts kinetically frozen in nanoporous carbon
• Nanostructured zeolite 4A molecular sieving air separation membranes
