Assignee:

BASF Corporation - Mt. Olive NJ

International Classification:

C08J 904
C08L 7508
C08K 53492
C08G 1848

US Classification:

521128

Abstract:

The invention pertains to flame retardant polyurethane foams prepared by the reaction of a polyoxyalkylene polyether polyol with an organic polyisocyanate and a blowing agent wherein melamine is incorporated as the sole flame retardant compound. The amount of melamine may range from about 10 weight percent to about 55 weight percent of the total composition.

Appl. No.:

7/340812

Inventors:

Steven D. Gagnon - Detroit MI
Edward M. Dexheimer - Grosse Ile MI

Assignee:

BASF Corporation - Parsippany NJ

International Classification:

C08L 7102

US Classification:

525409

Abstract:

A polyether polycarbonate block copolymer nonionic surface-active agent and method for making the same. The polyether polycarbonate surface active agent is comprised of a hydrophilic portion comprised of a polymer selected from the group consisting of a polyoxyalkylene polyether, a saccharide, a saccharide polyoxyalkylenate, a polycarbonate having a carbon dioxide content of from about 1 to 15 molar percent and mixtures thereof and a hydrophobic portion comprising alkylene and carbonate units arranged in alternating or random order to form a poly(alkylene carbonate) having a total carbon dioxide content of from about 25 to 50 molar percent and a total molecular weight of from about 300 to 10,000. The hydrophobic portion is bonded to the hydrophilic portion at each side of a reactive hydrogen. The surface active agent is prepared by polymerizing the hydrophilic portion with the hydrophobic portion in a weight ratio of about 10:90 to 90:10.

International Classification:

C08J 900

US Classification:

521 99

Abstract:

The flame retardancy of flexible polyurethane foams is increased by incorporation into the foam forming reactants of a low molecular weight, high primary hydroxyl trifunctional polyether polyol having a hydroxyl number between 300 and 500 and a primary hydroxyl content greater than 50 percent.
