US Patent:

43831028, May 10, 1983

Filed:

Jan 29, 1982

Appl. No.:

6/344127

Inventors:

Kenneth G. McDaniel - Round Rock TX
George P. Speranza - Austin TX

Assignee:

Texaco Inc. - White Plains NY

International Classification:

C08G 6700

US Classification:

528107

Abstract:

An improved method for the production of polyols useful in the application of sprayed high density polyurethane foams is described. The improvement involves varying the formaldehyde to phenol mole ratio to range between 1. 25:1 to 1. 75:1 to produce a polyol with the desired viscosity. Ordinarily such polyols are prepared by reacting 4. 65 to 5 moles of propylene oxide with 1 mole of the Mannich reaction product of a mole of phenol or nonylphenol with 1 or 2 moles of diethanolamine and 1 or 2 moles of formaldehyde. It is particularly surprising that such changes in the formulation may be made without adversely affecting the resultant properties of the spray foam.

Assignee:

Texaco Inc. - White Plains NY

International Classification:

C08G 1814

US Classification:

521131

Abstract:

Mixtures of aromatic polyols containing tertiary amine and ester functionalities suitable for use in rigid foams prepared by reacting a phthalic acid residue with an alkylene glycol and an amino alcohol are described. These novel polyols may be blended with conventional polyols to yield rigid polyurethane foams with better flammability resistance as compared with foams made from conventional polyols alone.

Appl. No.:

6/317708

Inventors:

Kenneth G. McDaniel - Round Rock TX

Assignee:

Texaco Inc. - White Plains NY

International Classification:

C08G 1814

US Classification:

521131

Abstract:

A polyurethane foam formulation for use primarily in sprayed applications has been discovered which provides a smoother than average foam surface. The formulation includes the addition of a primary or secondary mono or polyamine having a hydrogen functionality of two or greater. The compressive strengths of the resultant foams are equivalent to or greater than equivalent formulations without the amines, even though the amines also reduce fluorocarbon loss yielding lower density foams.

Appl. No.:

6/507815

Inventors:

Kenneth G. McDaniel - Round Rock TX

Assignee:

Texaco Inc. - White Plains NY

International Classification:

C08G 5964

US Classification:

536 50

Abstract:

An improved method is disclosed for producing amino polyols useful in preparing polyurethane foams. The improvement concerns charging ammonia, a primary amine or a secondary amine to the reaction vessel at the end of the oxide digestion step. The amine or ammonia scavenges the residual oxide and the resulting alkanol amine becomes one of the components of the polyol mixture. Alkanol amines are beneficial components of urethane polyols. In prior art industrial practice, residual oxide is vented to a scrubber system and then stripped to a low concentration.

US Classification:

521173

Abstract:

The preparation of isocyanurate foams from a recycled polyethylene terephthalate polyol modified with a polyethoxylated nonylphenol is disclosed. These modified foams exhibit improved fluorocarbon solubility. The foams may be used for building roofing and sheathing applications.

International Classification:

C08G 1814
C08G 1848
C08G 1832

US Classification:

521176

Abstract:

Covers a polyurethane elastomer of improved moldability, particularly useful in RIM applications which comprises the reaction product of an aromatic polyisocyanate, a high molecular weight polyether triol containing an internal mixed propylene oxide-ethylene oxide segment comprising 2-35% ethylene oxide by weight and 65-98% by weight of propylene oxide and an ethylene oxide cap such that said polyol has a primary hydroxyl content greater than 50% and preferably greater than 90%, and a chain-extending agent. Also covers the method of making said elastomer.

US Classification:

521175

Abstract:

The preparation of isocyanurate foams from a recycled polyethylene terephthalate polyol modified with aromatic amino polyols, sucrose polyols, ethoxylated alphamethyl glucosides, alkoxylated glycerine or alkoxylated sorbitol is disclosed. These modified foams exhibit improved fluorocarbon solubility. The foams may be used for building roofing and sheathing applications.

Appl. No.:

7/113642

Inventors:

Kenneth G. McDaniel - Austin TX

Assignee:

Arco Chemical Company - Newtown Square PA

International Classification:

C08G 1814

US Classification:

521137

Abstract:

The preparation of isocyanurate foams from a recycled polyethylene terephthalate polyol modified with alkoxylated amines and alkoxylated amides is disclosed. These modified foams exhibit improved fluorocarbon solubility, and do not cause the resultant polyols to be monofunctional, but rather difunctional. The foams may be used for building, roofing and sheathing applications.
