Abstract: Covers novel polyols comprising the reaction product of a 2,3-morpholinedione and a polyoxypropylene polyamine. Said polyols or alkoxylated derivatives thereof may be used in preparing polyurethane or polyisocyanurate polymers, particularly those polymers in cellular or foam form.

Abstract: Covers a method of producing polyurethanes formed as the reaction product of polyisocyanates and an alkoxylated novolak. Said novolak is the condensation product of a monohydric phenol and a 1,3-dioxane falling within the following structural formula: ##STR1## where R is selected from the group consisting of phenyl, substituted phenyl and gem dialkyl, and R.sub.1 is selected from the group consisting of hydrogen, alkyl, phenyl, and substituted phenyl. Also covers polyurethanes derived therefrom, and particularly rigid polyurethane foams.

Abstract: New catalysts for isocyanurate foams are those comprising aminomethacrylate salts. The foams are obtained by the polymerization of an aromatic polyisocyanate, and a polyether or polyester polyol in the presence of a blowing agent and said amino methacrylate salts falling within the following structural formula: ##STR1## where the radicals represented by R when taken singly are lower alkyl, and hydroxy lower alkyl, and when taken together with the adjacent nitrogen atom are selected from the group consisting of morpholino, C-substituted morpholino, N-alkylpiperazino and C-substituted N-alkylpiperazino, and M is selected from the group consisting of sodium, potassium, cesium, lithium and rubidium. The novel foams are useful in preparing rigid, flexible, semi-rigid, or semi-flexible materials such as panels, slabs or sprayed foam surfaces.

Abstract: The reaction product of salicylic acid esters and an alkylene oxide may be cyclized into a compound of the general formula: ##STR1## where R' is a radical selected from the group consisting of aryl, aliphatic and hydrogen. Specifically R' may be C.sub.1 -C.sub.10 alkyl, halogenated alkyl, alkyl ester, unsaturated aliphatic phenyl, substituted phenyl and hydrogen. These compounds are useful as antirhumatics. The compounds may also be converted into polyol crosslinking agents for polyurethane foams. These compounds may also be polymerized into polyesters by heating with a catalyst. Such a polymerization is a ring opening route and leaves no residue such as is found in condensation polymerization. Depending on the molecular weight attained these polyesters could be used as films, coatings and fibers, for example.

Abstract: Covers rigid polyurethane foams possessing unusual dimensional stability and heat distortion properties. Said foams are obtained by reacting in the presence of a blowing agent and a catalyst of polyurethane formation, an organic polyisocyanate and a polyol combination comprising 5-85 percent by weight of a copolymer of allyl alcohol and styrene and 15-95 percent by weight of a polyether polyol having a hydroxyl number ranging from about 200 to about 800, said weight percentages being based on the total weight of said polyol combination.

Abstract: A fire-retardant polyurethane such as a polyurethane foam is produced by reacting an amino polyol with a polyisocyanate in the presence of 2,4,5-tribromoimidazole acting as a fire-retardant agent. The polyurethane foam thus formd is particularly useful for insulation purposes.
