International Classification:

D02G 302

US Classification:

428364, 428365, 523205, 264555

Abstract:

Polymeric compositions include a nonaqueous additive system having dispersant-coated pigments physically dispersed in a liquid nonaqueous polymeric carrier which may be added directly to a melt flow of a polymeric host material. The additive system employed in the polymeric systems is most preferably in the form of a particulate paste which can be added in metered amounts (dosed) to a melt flow of the polymeric host material prior to being spun into filaments. By providing a number of additive systems having a number of different additive attributes, and controllably dosing one or more into the melt flow of host polymeric material, shaped objects of the polymeric material (e. g. , melt-spun filaments) having different additive attributes may be produced on a continuous basis without shutting down the shaping operation.

US Classification:

523351

Abstract:

Dispersible additive systems for polymeric materials include dispersant-coated pigments in a liquid nonaqueous polymeric carrier. The additive systems are most preferably in the form of a particulate nonaqueous paste which can be added in metered amounts (dosed) to a melt flow of the polymeric host material prior to being shaped (for example, prior to being spun into synthetic filaments). By providing a number of additive systems having a number of different additive attributes, and controllably dosing one or more into the melt flow of polymeric material, shaped objects of the polymeric material (e. g. , melt-spun filaments) having different additive attributes may be produced on a continuous basis without shutting down the shaping operation.

Appl. No.:

Assignee:

BASF Corporation - Mt. Olive NJ

International Classification:

C08K 900

US Classification:

523203

Abstract:

Additives for polymeric compositions are prepared by coating pigment with a dispersant, and thereafter dispersing the dispersant-coated pigment in a liquid nonaqeous polymeric carrier. Preferably, the dispersant-coated pigment is spray-dried. That is, most preferably, an aqueous dispersion of the pigment and dispersant is subjected to a spray-drying operation so as to obtain pigment coated with the dispersant. The dispersant-coated pigment will have an average particle size of about 5. mu. m or greater, but is capable of breaking apart to average particle sizes of about 1. mu. m or less when dispersed in a polymeric host material.
