Carbon-linked 5-hydroxymethylfurfural (HMF) oligomers contain at least one first HMF unit and one second HMF unit. The first and second HMF units are linked by a carbon-carbon bond with involvement of an aromatically bound carbon atom at position 3 or 4 of the furan ring of the first HMF unit. The HMF oligomers may be used as reactive carbonyl compounds in the manufacture of thermally curable resins on the basis of phenolic compounds and/or aminoplastic forming agents as well as in the manufacture of wood composite products.

A binding compound for mineral or organic fibres, includes from 40 to 95 wt % of furan resin, and from 5 to 60 wt % of at least one reducing sugar and/or of at least one non-reducing sugar, relative to the total dry weight of the composition, the binding composition having a dry matter content between 0.5 to 50 wt %.

An aqueous poly(furfuryl alcohol) solution contains: from 40% to 85% by weight of poly(furfuryl alcohol), from 15% to 60% by weight of water, and less than 1.5% by weight of furfuryl alcohol. The solution exhibits a pH of greater than 7.0, preferably of between 7.2 and 10.0. A process for the manufacture of a product based on mineral or organic fibers which are bonded by an organic binder can use such an aqueous poly(furfuryl alcohol) solution in the diluted form.

Aspects relate to a method of particle fabrication, comprising mixing at least one stabilizing compound with an aqueous solution to produce a first mixture, mixing furfuryl alcohol, a derivative of furfuryl alcohol, or a mixture thereof, into the first mixture to produce a second mixture, heating the second mixture, mixing a surfactant comprising an acid moiety (e.g., an alkylbenzene sulfonic acid) and the second mixture to produce a third mixture, initiating a polycondensation reaction of the furfuryl alcohol, the derivative of the furfuryl alcohol, or the mixture thereof, in the third mixture to produce polymer (or polymer-derived) particles comprising polyfurfuryl alcohol, and (optionally) defining or modifying the glass transition temperature of the polymer or polymer-derived particles comprising polyfurfuryl alcohol.

Composition including a first component, including furfuryl alcohol and humins and a second component including an acidic polymerization initiator. The composition can be oligomerized to a resin, which has a viscosity in the range of 0.1 to 10,000 Pa.Math.s at 25 C., determined according to ISO3219. The resin, or a blend of furfuryl alcohol and humins as a component A and an acidic polymerization initiator as a component B, separated from each other, may form a kit for an adhesive or impregnation agent.
