C08F 402
C08F 424
C08F 1000
C08F 1002

US Classification:

526106

Abstract:

A method is provided for treating a hydrogel with a saturated, aliphatic alcohol selected from the group consisting of 1-pentanol, 2-pentanol, 3-methyl-1-butanol, 4-methyl-2-pentanol, 2,2-dimethyl-1-propanol and 1-hexanol to remove water thereby producing a dried product that retains a porous structure and is particularly suitable upon impregnation with a polymerization catalyst for use in promoting the production of ethylene polymers of melt index in excess of about 6. 6.

Richard E. Dietz - Borger TX

International Classification:

C08F 402
C08F 1000

US Classification:

526119

Abstract:

A transition metal compound and a metal halide compound are chemically combined to form a composition of matter. The composition of matter is rapidly mixed with a precipitating agent to form an active olefin polymerization catalyst.

International Classification:

C08F 466
C08F 1002

US Classification:

526129

Abstract:

Polymerization of olefins in the presence of a catalyst system comprising a titanium-containing component A associated with a chemically treated silica-containing composition and a dihydrocarbylmagnesium compound and a cocatalyst component B comprising metal hydride or organometal compound derived from an element of Groups IA-IIIA of the Periodic Table.

Filed:

Aug 12, 1980

Appl. No.:

6/177313

Inventors:

Richard E. Dietz - Borger TX

Assignee:

Phillips Petroleum Company - Bartlesville OK

International Classification:

C08F 464
C08F 468

US Classification:

252429B

Abstract:

A transition metal compound and a metal halide compound are chemically combined to form a composition of matter. The composition of matter is rapidly mixed with a precipitating agent to form an active olefin polymerization catalyst under an olefin atmosphere and prepolymer is formed on said catalyst to yield a catalyst capable of producing low fines content polymer.

Appl. No.:

6/363681

Inventors:

Max P. McDaniel - Bartlesville OK
James N. Short - Bartlesville OK

Assignee:

Phillips Petroleum Company - Bartlesville OK

International Classification:

C08F 402

US Classification:

502117

Abstract:

In accordance with one embodiment of this invention, a bis-(cyclopentadienyl)chromium(II) compound is introduced onto an activated phosphate-containing support and utilized in conjunction with an organometal cocatalyst, such as an alkylaluminum. In accordance with another embodiment of this invention, a phosphate-containing zerogel is formed by removing water from an aluminum phosphate-containing hydrogel by means of azeotropic distillation or washing with a volatile, water miscible organic compound, activated and thereafter a bis-(cyclopentadienyl)chromium(II) compound is incorporated therewith. In other embodiments of this invention, a phosphate-containing support is formed by forming aluminum phosphate from an aluminum alkoxide or from a melt, or by phosphating silica or alumina, or by forming an aluminum phosphate/silica combination. A support thus formed is activated and a bis-(cyclopentadienyl)chromium(II) compound added. Alternatively in all embodiments, the chromium and phosphate components can be added separately.
