15248 IUPAC Gold Book - furan polymer 10.1351/goldbook.15248 15248 current 1 Polymer prepared from furan or a furan derivative. The most widely used furan polymers are linear, branched, and network polymers prepared from (2-furyl)methanol, such as poly(furan-2,5-diylmethylene). Furan polymers prepared from furan-2-carbaldehyde (formerly furfural), such as poly(furan-2,5-diylcarbonyl), are usually referred to as furfural polymers, and they are conjugated polymers. Branching and network formation can occur through the condensation of methylene groups with terminal \(\ce{-CH2OH}\) groups. Comonomers such as phenols, aldehydes, and ketones are often used in preparation of furan polymers. Use of the terms "furan resin" or "furfural resin" for "furan polymer" or "furfural polymer", respectively, is discouraged. PAC, 2009, 81, 1131.
