US Patent:

RE290149, Oct 26, 1976
Filed:

Aug 25, 1975
Appl. No.:

5/607134
Inventors:

Louis C. Pizzini - Trenton MI
Gerhard G. Ramlow - East Windsor NJ
John T. Patton - Wyandotte MI
William W. Levis - Wyandotte MI
Assignee:

BASF Wyandotte Corporation - Wyandotte MI
International Classification:

C08L 2902
C08F 214
C08F 1604
US Classification:

260 332R
Abstract:

Highly-stable graft copolymer dispersions are prepared by the in situ polymerization in the presence of a free radical catalyst of a vinyl monomer in a polyol containing an essential amount of unsaturation. The dispersions are low-viscous liquids which may be advantageously employed in the preparation of flexible urethane foams having enhanced load-bearing properties.

US Patent:

40935736, Jun 6, 1978
Filed:

Jan 17, 1977
Appl. No.:

5/759978
Inventors:

Gerhard G. Ramlow - Grosse Ile MI
Louis C. Pizzini - Trenton MI
John T. Patton - Wyandotte MI
John R. Murphy - Trenton MI
Assignee:

BASF Wyandotte Corporation - Wyandotte MI
International Classification:

C08G 1863
US Classification:

260 25BE
Abstract:

Low-viscous, stable polymer dispersions are prepared by blending a hydroxy-containing finely-divided solid polymer with a polyol having an equivalent weight between 500 and 10,000. The resulting dispersions are particularly useful in the preparation of polyurethanes having enhanced physical properties particularly load bearing or hardness, tensile strength and tear resistance.

US Patent:

43595413, Nov 16, 1982
Filed:

Jan 19, 1981
Appl. No.:

6/225935
Inventors:

John T. Patton - Wyandotte MI
Gerhard G. Ramlow - Grosse Ile MI
Assignee:

BASF Wyandotte Corporation - Wyandotte MI
International Classification:

C08G 1814
C08G 1875
C08G 1877
US Classification:

521137
Abstract:

Polyisocyanurate polymers are prepared by polymerization of polyisocyanates in organic solvents employing trimerization catalysts. The polyisocyanates are reacted with monofunctional active hydrogen compounds prior to polymerization or subsequent to the polymerization. These polymers may be dispersed in polyols for the preparation of cellular and non-cellular polyurethane products having improved physical properties.

Appl. No.:

6/225934
Inventors:

Gerhard G. Ramlow - Grosse Ile MI
Peter T. Kan - Plymouth MI
Assignee:

BASF Wyandotte Corporation - Wyandotte MI
International Classification:

C08G 1879
C08K 506
US Classification:

524871
Abstract:

Polyisocyanurate polymers are prepared by the polymerization of organic polyisocyanates in organic solvents employing trimerization catalysts. After deactivation of the catalysts and removal of the solvents, these polymers may be dispersed in polyols which are employed for the preparation of cellular and non-cellular polyurethane products displaying improved load bearing properties.

Filed:

Mar 3, 1983
Appl. No.:

6/471722
Inventors:

Gerhard G. Ramlow - Grosse Ile MI
Duane A. Heyman - Monroe MI
Oscar M. Grace - Madison Heights MI
Assignee:

BASF Wyandotte Corporation - Wyandotte MI
International Classification:

C08K 506
C08K 510
C08L 2902
C08L 5108
US Classification:

521137
Abstract:

White graft polymer dispersions in polyoxyalkylene polyether polyols are employed together with flame retardant compounds to prepare flame retardant polyurethane foams. The polymer dispersions employ less than 0. 1 mole of induced unsaturation per mole of polyol mixture. Improved processes for the preparation of these polymer dispersions employ either maleate or fumarate derived polyetherester polyols or polyetherester polyols prepared by reacting a polyoxyalkylene polyether polyol with a compound selected from the group consisting of maleic acid, maleic anhydride and fumaric acid and an alkylene oxide in the presence of salts and oxides of divalent metals.
