Abstract: A polyol comprising an alkoxylated modified resole, said modified resole being formed by the reaction of(i) a phenolic compound and/or mixtures of homologues thereof,(ii) urea and/or melamine,(iii) an organic primary and/or secondary amine group-containing compound, and(iv) an aldehyde.

Abstract: The instant invention is directed to a process for the production of an inorganic-organic foam composition comprising reacting an organic, nonionic hydrophilic polyisocyanate with an aqueous alkali metal silicate in the presence of a catalyst and a blowing agent, the improvement wherein said aqueous alkali metal silicate contains from 0.1 to 15% by weight, based on the weight of the aqueous alkali metal silicate, of a compound of the formula: ##STR1## wherein A is selected from the group consisting of N, P and S, wherein R, R', R" and R'" may be the same or different and are selected from the group consisting of allyl, vinyl, C.sub.1 to C.sub.17 alkyl or mono- or polyhydroxy substituted alkyl, C.sub.6 to C.sub.10 aryl or mono- or polyhydroxy substituted aryl, C.sub.7 to C.sub.22 aralkyl or mono- or polyhydroxy substituted aralkyl, and C.sub.7 to C.sub.
