Appl. No.:

7/326818

Inventors:

John R. Damewood - Spartanburg SC
Jill R. Menzel - Spartanburg SC
Fred N. Teumac - Spartanburg SC
Bert A. Ross - Spartanburg SC

Assignee:

Reeves Brothers, Inc. - Spartanburg SC

International Classification:

C08L 7508
C08L 7514
C08L 7516

US Classification:

525455

Abstract:

The processing temperature of linear thermoplastic polyurethane elastomers prepared from a polycarbonate polyol, a polyether polyol, an extender and a disocyanate compound which has been modified by reaction with a low molecular weight diol to form a modified diisocyanate compound prior to reaction with the other components of the elastomer, can be reduced by adding a millable thermoplastic linear polyurethane elastomer thereto. These materials possess an optimum combination of hydrolytic stability, toughness, flexibiity and low temperature processing characteristics.

International Classification:

C08G 1814

US Classification:

521107

Abstract:

Compositions and methods for providing a flexible flame retardant polyether polyurethane foam prepared from foam forming components of a polyether polyol, an organic isocyanate compound, water, a liquid phosphorus ester in an amount of about 4 to 10 parts by weight and melamine in an amount of 1 to 5 parts by weight, each based on 100 parts by weight of the polyether polyol in the composition. Between 15 and 500 percent by weight melamine is used to replace a minor portion of the amount of ester (i. e. , less than half) which would normally be used to achieve substantially the same degree of flame retardance in the foam.

International Classification:

C08J 900

US Classification:

521128

Abstract:

Flexible polyurethane foam prepared from foam forming compositions of a polyether polyol, an organic isocyanate compound, a blowing agent, and a curing agent of a melamine derivative in an amount effective to rapidly cure the resultant foam and improve the compression set properties of the foam, the amount of curing agent generally ranging from about 0. 01 up to about 2 parts by weight based on 100 parts polyether polyol. Also, flame retardant polyether polyurethane foam prepared from foam forming components of a polyether polyol, an organic isocyanate compound, water, a liquid phosphorus ester in an amount of about 4 to 10 parts by weight and the curing agent in an amount of 0. 4 to 2 parts by weight, each based on 100 parts by weight of the polyether polyol in the composition. The most preferred curing agent has the formula C. sub. 3 N. sub. 6 (R. sub. 2). sub. x (R. sub. 1). sub. 6-x wherein R. sub.

International Classification:

C08L 7500
C08L 7700

US Classification:

525131

Abstract:

Thermoplastic synthetic polymeric compositions of certain polyurethanes, polyamides or chlorinated polyolefins, having processing temperatures in the range of about 150. degree. to 325. degree. F. , can be modified by the addition of a millable thermoplastic polyurethane elastomer thereto to lower the processing temperature by 10. degree. to 30. degree. F. or more. This modification enables the thermoplastic composition to be processed on conventional calendering or extrusion equipment with a lesser amount of energy or with better performance. Also, coated fabrics of such thermoplastic compositions and a fiber reinforcement.

International Classification:

C08K 515

US Classification:

523100

Abstract:

A liner composition for a potable fluid container closure element which includes an inorganic sulfite such as sodium sulfite and/or a tocopherol compound such as a dl-. alpha. -tocopherol (vitamin E) for preventing off-flavors due to the presence of aldehydes in the fluid. Also, a potable fluid container of a reservoir element for containing a potable fluid, the reservoir element having an opening, a closure element capable of being attached to the opening, and the liner composition associated with the closure element. Also, a method of improving the taste of a potable fluid such as bottled water by use of the container and one of the previously described liner compositions associated therewith. Also, an improved method for processing the composition into closure liners based upon the prevention of the development of off-flavor-causing substances therein.

US Classification:

521107

Abstract:

Methods for rapidly curing flexible polyether-derived foam in situ by adding to the foam forming composition an ammonia containing material having a decomposition temperature below the temperature of the highest reaction exotherm of the foam-forming composition and decomposing the ammonia containing material by exposure to the heat of the exotherm produced by reaction of the foam-forming components to release ammonia to cure the foam by contact therewith.
