US Patent:

50379100, Aug 6, 1991

Filed:

Oct 17, 1989

Appl. No.:

7/422469

Inventors:

Gregory A. Cook - Baton Rouge LA
Theodore R. Engelmann - Baton Rouge LA

Assignee:

Paxon Polymer Company, L.P. - Baton Rouge LA

International Classification:

C08F 4651
C08F 1000

US Classification:

526128

Abstract:

A method of manufacturing a polyolefin using a catalyst system of an ingredient (A) and ingredient (B), with ingredient A being obtained through successive reaction steps. Ingredient A is prepared by forming a mixture of (1) the combination of (a) metallic magnesium or an oxygen-containing organic compound of magnesium with (b) a mixture of a monohydroxylated organic compound and a polyhydroxylated organic compound, and (2) oxygen-containing organic compounds of titanium. The resulting solution is reacted in sequence with (3) at least one first halogenated aluminum compound, (4) at least one silicon compound and (5) at least one second halogenated aluminum compound. Compounds 3 and 5 are added at temperatures not exceeding about 25. degree. C. Ingredient B is an organometallic compound of metals from Group Ia, IIa, IIIa or IVa of the Periodic Table. The resulting free-flowing polyolefin is characterized by a large average particle size and small amount of fine particles.

Appl. No.:

7/632780

International Classification:

C08L 501
C08L 9106

US Classification:

524475

Abstract:

Emulsifiable linear polyethylene compositions which exhibit good hardness and color characteristics can be obtained by oxidizing a blend of about 90 to 60% by weight of either linear low density polyethylene or high density polyethylene and about 10 to 40% by weight paraffin wax to an acid number of 12 to 30 mg KOH/g. The water emulsions obtained from the emulsifiable polyethylene compositions are useful as textile lubricants and fruit coatings.
