    • A polymer derived by heating in the presence of an acid catalyst at between about 65.degree. C. and 260.degree. C.I. a reaction product, a cogeneric mixture of alkoxy functional compounds, having average equivalent weights in the range from about 220 to about 1200, obtained by heating in the presence of a strong acid at about 50.degree. C. to about 250.degree. C.(a) a diaryl compound selected from naphthalene, diphenyl oxide, diphenyl sulfide, their alkylated or halogenated derivatives or mixtures thereof,(B) formaldehyde or formaldehyde-yielding derivative,(C) water, and(D) a hydroxy aliphatic hydrocarbon compound having at least one free hydroxyl group and from 1 to 4 carbon atoms, which mixture contains up to 50 percent by weight unreacted (A); withIi. at least one monomeric phenolic reactant selected from the group ##STR1## WHEREIN R is selected from the group consisting of ##STR2## HYDROGEN, ALKYL RADICAL OF 1-20 CARBON ATOMS, ARYL RADICAL OF 6-20 CARBON ATOMS, WHEREIN R.sub.1 represents hydrogen, alkyl or aryl, m represents an integer from 1 to 3; o represents an integer from 1 to 5; p represents an integer from 0 to 3; X represents oxygen, sulfur or alkylidene; and q represents an integer from 0 to 1; and,Iii. optionally an aldehyde or an aldehyde-yielding derivative or a ketone,For from several minutes to several hours.These polymeric materials are liquids or low melting solids which are capable of further modification to thermoset resins. These polymers are capable of being thermoset by heating at a temperature of from about 130.degree. C. to about 260.degree. C. for from several minutes to several hours in the presence of a formaldehyde-yielding compound. These polymers are also capable of further modification by reacting under basic conditions with formaldehyde with or without a phenolic compound. The polymers, both base catalyzed resoles and acid catalyzed novolacs are useful as laminating, molding, film-forming and adhesive materials. The polymers, both resoles and novolacs, can be epoxidized as well as reacted with a drying oil to produce a varnish resin.

    • Liquid oxyalkylated polyol prepolymers are prepared by oxyalkylating a prepolymer prepared from a hydroxy aromatic compound, an aldehyde and furfuryl alcohol with an alkylene oxide containing about 2-4 carbon atoms. The oxyalkylated polyol prepolymers have a viscosity of 1000-500,000 centipoises at 25.degree. C. and contain about 1.1-6 moles of interpolymerized aldehyde, about 3.1-15 moles of interpolymerized furfuryl alcohol, and about 1-10 moles of interpolymerized alkylene oxide for each mole of interpolymerized hydroxy aromatic compound. The resultant prepolymers are highly reactive and may be further polymerized with or without monomers such as polyisocyanate to produce flame retardant solid or cellular interpolymers. Flame retardant solid or cellular polyurethanes are prepared in one variant by interpolymerizing organic polyisocyanates with the oxyalkylated polyol prepolymers. In another variant, flame retardant closed cell cellular interpolymers are provided. Processes are provided for preparing the aforementioned novel oxyalkylated polyol prepolymers and solid or cellular interpolymers.
