Appl. No.:

09/917310

International Classification:

C08F 800

US Classification:

525387, 5253338

Abstract:

Polypropylene heterophasic copolymers are produced having increased impact strength through the use of controlled rheology techniques by the addition of a peroxide at conditions which increase the deactivation or half life of the peroxide. The increased half life slows down the vis-breaking process and allows better dispersion of rubber particles within the polymer. In this way, copolymers having a high melt flow can be prepared while obtaining high impact strength and lower stiffness values, without the need for additional elastomeric modifiers.

US Classification:

524236, 524106, 525391, 428331

Abstract:

A process for the production and treatment of a stereoregular propylene polymer such as isotactic polypropylene. The isotactic polypropylene can be produced by catalysis employing a metallocene catalyst or employing a Ziegler-Natta catalyst. A polymerization reactor is operated to provide for the reaction of propylene supplied to the reactor to produce a stereoregular propylene polymer fluff. A product stream containing unreacted propylene and the propylene polymer fluff is withdrawn from the polymerization reactor. The product stream is treated to separate at least a portion of the unreacted propylene from the product stream. The polymer fluff is heated to a temperature sufficient to melt the propylene polymer. Incorporated into the propylene polymer fluff in an amount within the range of 0. 01-0. 08 wt. % is a tertiary amine formula: wherein R is an aliphatic group containing 8-18 carbon atoms and Râ and Râ are each independently a hydroxyalkyl group containing from 1 to 3 carbon atoms.

International Classification:

D01D 512

US Classification:

2642108

Abstract:

Process for the production of fibers formed from an ethylene-propylene copolymer characterized as a random copolymer of ethylene and isotactic polypropylene having a random ethylene content within the range of 2-12 mole %. The propylene content of the copolymer can have an isotacticity of at least 90% meso diads. The copolymer is heated to a molten state and then extruded to form a fiber preform. The fiber preform is subject to a spinning speed of at least 500 meters per minute. This is followed by drawing the spun fiber preform at a draw ratio within the range of 1:1-6:1 to produce a continuous fiber of the ethylene-propylene copolymer. A specific ethylene-propylene copolymer has an ethylene content within the range of 6-8%.

US Classification:

2642108, 26421112, 26421114

Abstract:

A method for the production of polypropylene fibers from a propylene polymer including isotactic polypropylene produced by the polymerization of propylene in the presence of an isospecific metallocene catalyst. The polymer is heated to a molten state and extruded to form a fiber preform at a temperature within the range of about 170-210 C. The fiber preform is spun at a spinning speed of at least 200 meters per minute and quenched at a heat transfer rate of no more than 12 joules per second fiber. The spun fiber is then subjected to a winding operation. The fiber may be drawn subsequent to the quenching operation and prior to winding. The cooled fiber preform may be drawn to produce a fiber at a draw ratio within the range of about 1. 5-4. 0 with shrinkage of the fiber over the range of the draw ratio at a variance of 25% of the median of the shrinkage factor over the draw ratio.

US Classification:

525240, 525191, 428343

Abstract:

A polypropylene material is prepared from a blend of heterophasic propylene copolymers and propylene homopolymers. The material is prepared by blending the polymers while they are in a molten state, and forming a film or sheet from the polymer blend. The material has particular application to forming slit film tapes and similar materials. The resultant materials exhibit increased tenacity, elongation and toughness and greater surface roughness as compared to those materials prepared solely from propylene homopolymers.

Abstract:

A heat-seal polymer film and method of forming such film is provided. The heat-seal film is formed from metallocene-catalyzed isotactic random copolymers of propylene and at least one other Cto Calpha olefin, such as ethylene random.
