    摘要： A method for the preparation of &ggr;-hydroxy ethers from cyclic organic carbonates and active-hydrogen-containing compounds in one form includes the steps of contacting an active-hydrogen-containing compound and a cyclic organic carbonate compound containing a six-membered ring, and a catalyst, running the reaction at a suitable temperature, and isolating the &ggr;-hydroxy ether as a mixture that can be purified or used directly as produced in the reaction.

    摘要： An improved method for preparing amino polyols is disclosed. The method is the Mannich condensation of phenol, formaldehyde and diethanolamine in a molar ratio of (1:1:1), and then alkoxylation with a mixture of ethylene oxide and propylene oxide in a weight ratio of about 5:95 to 20:80 to form an amino polyol of hydroxyl number 440 to 515.The method gives higher yields of aromatic amino polyols of lower viscosity than those of the comparative example.

    摘要： A process for the accelerated cure of an epoxy resin is disclosed. The resulting epoxy resin may be used in protective coatings, adhesives, seamless and terrazo flooring and caulking and sealing compositions. The resulting resin system is also useful, for example, in casting, potting, in escapulating, grouting and patching. The process involves mixing an epoxy resin of the polyhydric phenol, polyglycidyl ether type with a novel accelerator-hardener which is a condensation product of phenol, formaldehyde and an aminoalkylene derivative of a polyoxyalkylenepolyamine.

    摘要： 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.
