Abstract

1365094 Modified furfuryl alcohol polymers; foundry moulds CIBA-GEIGY AG 13 July 1972 [3 Aug 1971] 36531/71 Headings C3R C3P and C3N Polymers (I) of furfuryl alcohol (II) are cured by reaction with a polyisocyanate (III). I are defined either as polymerizates of II per se obtained by reaction in an acid medium or as condensates of II and formaldehyde, e.g. in a molar ratio II: HeHo of 1 : 0À1 to 1 : 1À5. III exemplified is bis(4-isocyanatophenyl)methane (IV). The polymers are useful in preparing foundry moulds and cores. These may be prepared by coating sand with a binder of I in 2-butoxyethanol with 2(diethylamino)ethanol catalyst and 3-N-(ethylamino)propyltriethoxysilane (coupling agent). A second batch of sand is treated with IV, the two batches being brought together, rapidly stored and compressed when cure takes place.
