Abstract

1408873 Polyfuran foams made from furfuryl alcohol KONINKLIJKE EMBALLAGE INDUSTRIE VAN LEER NV 13 Sept 1972 [15 Sept 1971] 43033/71 Headings C3C and C3P A polyfuran foam is made by adding at least 4% by wt. (based on the total wt. of furfuryl alcohol, and if present its prehomo- and/or preco-polymer) of a liquid catalyst comprising (a) at least one acid having a pKa in water of 1-4 and/or (b) at least one acid having a pKa in water of less than 1 uniformly distributed throughout an alcohol which does not polymerize under the reaction conditions to a liquid feed material to effect polymerization and foaming thereof, the liquid feed comprising furfuryl alcohol optionally in admixture with a furfuryl alcohol prehomo- and/or preco-polymer and/or one or more copolymerizable materials but does not contain an alcohol (other than furfuryl) or an aromatic hydrocarbon, at least 50% of the hydroxyl groups of any mixture of furfuryl alcohol with the prepolymer being derived from free furfuryl alcohol, and any prepolymer being so selected that the mixture thereof with furfuryl alcohol has a viscosity of not more than 1150 cp. at 25‹ C. In the examples foams were made by polymerizing a mixture of furfuryl alcohol, its prepolymer, a silicone, paraformaldehyde (as blowing agent or foam stabilizer, flint, a volatile liquid blowing agent, butanediol, o-phosphoric acid, p-toluene sulphonic acid, sulphuric acid, n-butanol, dipropyleneglycol, dodecyl alcohol, polyethylene glycol, methanol, propan-2-ol, boric acid, magnesium sulphate, tetraphosphoric acid, kaolin, iron powder and/or 2-butoxy-ethanol.
