US Patent:

51644223, Nov 17, 1992

Filed:

Nov 25, 1991

Appl. No.:

7/796956

Inventors:

Michael E. Londrigan - Clearwater FL
Scott C. Snider - St. Petersburg FL
Kenneth G. Trout - Tampa FL

Assignee:

The Celotex Corporation - Tampa FL

International Classification:

C08G 1800

US Classification:

521159

Abstract:

An isocyanate-terminated quasi-prepolymer is prepared by reacting an organic polyisocyanate and a polyester polyol which comprises the reaction product of a polycarboxylic acid component and ethylene glycol or a mixture of ethylene glycol and at least one other glycol. The use of the quasi-prepolymer in the preparation of rigid cellular polymers, especially polyisocyanurate foams, enhances the thermal insulating properties of the foams, and helps to reduce their cost and blowing agent usage.

International Classification:

C08J 900

US Classification:

521112

Abstract:

A closed cell, rigid polyisocyanurate foam which comprises the reaction product of a polyisocyanate and a polyol in the presence of (a) a hydrogen-containing blowing agent or a mixture of a hydrogen-containing blowing agent and at least one co-blowing agent, and (b) a siloxane oxyalkylene copolymer (i) having a molecular weight below about 7500 and an oxyalkylene portion containing greater than 60 weight percent of oxyethylene units and (ii) being prepared by the reaction of an organohydrogensiloxane with a polyoxyalkylene in an essentially solventless system or in the presence of a high boiling point polar polyol.

Kenneth G. Trout - Tampa FL

Assignee:

The Celotex Corporation - Tampa FL

International Classification:

C08J 900

US Classification:

521125

Abstract:

Rigid, closed cell polyisocyanurate foams are prepared by reacting together a polyisocyanate and a polyester polyol or a mixture of a polyester polyol and at least one other isocyanate-reactive compound in the presence of (a) a hydrogen-containing blowing agent or a mixture of a hydrogen-containing blowing agent and at least one co-blowing agent and (b) a catalyst mixture comprising (i) a carboxylate salt of an alkali metal or an alkaline earth metal or mixtures thereof, (ii) a tertiary amine, and (iii) a quaternary ammonium carboxylate salt, wherein the mole ratio of carboxylate metal salt: tertiary amine is a value less than about 2:1, and the total moles of quaternary ammonium carboxylate salt are less than the combined moles of the carboxylate metal salt and the tertiary amine.

Assignee:

Jim Walter Reasearch Corp. - St. Petersburg FL

International Classification:

B32B 2700

US Classification:

428336

Abstract:

A synthetic board is prepared by a process of contacting lignocellulosic material with a binder and subsequently forming the treated material into a board by the application of heat and pressure, wherein (a) the binder comprises an organic polyisocyanate and a reactive hydrogen-containing component, especially an aromatic polyester polyol, and (b) the lignocellulosic material is additionally contracted with a surfactant.

International Classification:

B32B 2700

US Classification:

428288

Abstract:

A binder/release system for the preparation of molded articles, especially lignocellulosic composites, which utilizes in combination with isocyanate-based binders a fatty material as an internal and/or external release agent, the fatty material being at least one polymerized fatty acid and/or at least one polycarboxyl compound containing a polymeric fatty radical(s).

Assignee:

Jim Walter Research Corp. - St. Petersburg FL

International Classification:

C08G 1814

US Classification:

521131

Abstract:

Rigid cellular polymers are made by reacting an isocyanate-terminated quasi-prepolymer with a polyol component comprising a polyester polyol having a free glycol content of less than about 7 percent by weight of the polyester polyol in the presence of a blowing agent. The combined use of the quasi-prepolymer and the polyester polyol enhances the thermal insulating properties of the foams.
