US Patent:

44422377, Apr 10, 1984

Filed:

Nov 22, 1982

Appl. No.:

6/443726

Inventors:

Robert L. Zimmerman - Austin TX
Kenneth G. McDaniel - Round Rock TX

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.

Filed:

Oct 28, 1985

Appl. No.:

6/791679

Inventors:

Kenneth G. McDaniel - Austin TX

Assignee:

Texaco Inc. - White Plains NY

International Classification:

C08G 1814
C08G 1816
C08G 1832
C08G 1834

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.

Filed:

Jan 22, 1986

Appl. No.:

6/821319

Inventors:

Kenneth G. McDaniel - Austin TX

Assignee:

Texaco Inc. - White Plains NY

International Classification:

C08G 1814
C08G 1832
C08G 1834
C08G 1842

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.

US Patent:

47601000, Jul 26, 1988

Filed:

Oct 26, 1987

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.

Filed:

Oct 24, 1985

Appl. No.:

6/791015

Inventors:

Michael E. Brennan - Austin TX
Kenneth G. McDaniel - Austin TX
Howard P. Klein - Austin TX

Assignee:

Texaco Inc. - White Plains NY

International Classification:

C08G 1814
C08G 1832

US Classification:

521167

Abstract:

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.
