Appl. No.:

7/769263

Inventors:

James D. McCullough - Houston TX

Assignee:

Shell Oil Company - Houston TX

International Classification:

C08L 2310
C08L 2326
C08L 2318
C08F29708

US Classification:

525322

Abstract:

Polypropylene impact copolymer compositions and visbroken derivatives thereof demonstrate a good balance of low temperature properties and resistance to stress whitening when the homopolymer phase is at least predominantly homopolymeric polypropylene and the rubber phase comprises a major proportion of ethylene with a minor proportion of. alpha. -olefin of at least 4 carbon atoms and a minor proportion of propylene.

Inventors:

Ananda Mohan Chatterjee - Katy TX
James Douglas McCullough - Houston TX

Assignee:

Union Carbide Chemicals & Plastics Technology Corporation - Danbury CT

International Classification:

C08L 2312
C08L 2316

US Classification:

525240

Abstract:

The present invention relates to compositions containing impact copolymer compositions that are a blend of a propylene polymer phase and a rubber phase in which the ethylene content of the rubber phase is between about 75 to about 95% by weight. The rubber content of the impact copolymer composition ranges between about 35% by weight to about 60% by weight. The crystallinity of the high ethylene-content rubber phase provides overall improvement in film properties and also balance of film tensile properties in the machine and transverse directions. Compared to traditional impact copolymer compositions having a low ethylene content-rubber phase, the inventive copolymers have significantly enhanced melting and crystallization peaks due to polyethylene-like crystallinity in the rubber phase.

Appl. No.:

7/498886

Inventors:

James D. McCullough - Houston TX

Assignee:

Shell Oil Company - Houston TX

International Classification:

C08F 200
C08F29708

US Classification:

525 53

Abstract:

In the gas phase, two stage process for the production of polypropylene impact copolymer, the fouling of the second stage recycle loop and the heat exchange unit incorporated therein is reduced by the addition to the substantially gaseous material passing through the loop of a small amount of alkylene compound selected from alkylene glycol compounds, alkylene glycol derivatives of alkylene diamines or ethers or esters thereof.

8/273550

Inventors:

Chin-Yuan George Ma - Sugar Land TX
James Douglas McCullough - Houston TX

Assignee:

Shell Oil Company - Houston TX

International Classification:

C08L 520

US Classification:

524230

Abstract:

Appl. No.:

7/785720

Inventors:

Paul K. Casey - Houston TX
James D. McCullough - Houston TX
Charles C. Hwo - Sugar Land TX

Assignee:

Shell Oil Company - Houston TX

International Classification:

C08J 1104

US Classification:

521 405

Abstract:

A method for processing of recyclable polymeric materials comprising the addition of a relatively lower shear viscosity polybutylene and optionally at least one filler to these recyclable materials prior to or during processing. Products produced by this process have and exhibit improved performance properties.

Filed:

Dec 23, 1998

Appl. No.:

9/220180

Inventors:

James Douglas McCullough - Houston TX

Assignee:

Union Carbide Chemicals & Plastics Technology Corporation - Danbury CT

International Classification:

C08F 600

US Classification:

528480

Abstract:

A method of deactivating a polyolefin polymer is disclosed whereby the polymer is contacted in a post-reactor vessel with CO. sub. 2 and then an acid acceptor and at least one secondary antioxidant are incorporated into the deactivated polyolefin polymer. The resulting product displays improved color and reduced melt flow breaking tendency, and does not exhibit polymer agglomeration and stickiness.

Appl. No.:

8/542719

Inventors:

James D. McCullough - Houston TX
John F. Bradford - Katy TX

Assignee:

Union Carbide Chemicals & Plastics Technology Corporation - Danbury CT

International Classification:

C08F 804

US Classification:

5253338

Abstract:

A process for reacting molten polyolefin with a free radical generator wherein the molten polyolefin passes through an extruder and free radical generator is mixed with the molten polyolefin in increments along the extruder such that any previously added free radical generator is decomposed before the next increment of free radical generator is added to the molten polyolefin. Products of the process demonstrate improved efficiency of free radical generator utilization as measured by enhanced melt flow rates relative to the total amount of free radical generator used.
