Patent Number Title Of Patent Date Issued
6800700 Polymerizations using adjuvant catalysts October 5, 2004
Disclosed herein are methods for producing polymeric materials which are normally tenacious in their character to such degree that their processing by conventional means is not possible, for example substantially-amorphous polyolefins. By introducing a second catalyst capable of producin
6143842 Elastomeric polyolefins production and recovery November 7, 2000
Disclosed herein are novel polymers and copolymers of alphaolefins produced using various Ziegler/Natta and Metallocene catalysts. Commercial production of these polymers is now possible for the first time owing to the polymer harvesting technology also disclosed herein.
6100351 Olefin polymerization process and products thereof August 8, 2000
Methods of producing polyolefin polymers by polymerizing an .alpha.-olefin in the presence of a catalyst including a pro-catalyst having a magnesium halide, an aluminum halide, a tetravalent titanium halide, an electron donor, and a silane having the formula R.sub.1 R.sub.2 Si(OR.sub.3)
6080818 Polyolefin blends used for non-woven applications June 27, 2000
The invention relates to methods for preparing a fiber, thread or yarn including a polymer blend of a predominantly atactic flexible polyolefin polymer having a high weight average molecular weight of at least about 100,000 and a heat of fusion of about 15 to 60 J/g with an isotactic
6017615 Film product comprising novel polyolefins January 25, 2000
Multi-layer film products comprising an inner or core layer made from polyolefin polymers produced by polymerizing an .alpha.-olefin in the presence of a catalyst including: a pro-catalyst having a magnesium halide; an aluminum halide; a tetravalent titanium halide, ;an electron dono
5948720 Catalyst for the production of flexible polyolefin compositions, methods for making and using sa September 7, 1999
A catalyst for use in the production of flexible polyolefins using a pro-catalyst of (a) a magnesium halide, (b) an aluminum halide, (c) a tetravalent titanium halide, (d) an electron donor comprising at least one of 2,6-lutidine, 6-chloro-2-picoline, or 2,6-dichloropyridine; and (e) a
5948447 Apparatus for product recovery of polyolefings September 7, 1999
A method and apparatus for product recovery of polyolefins, particularly high molecular weight amorphous poly alphaolefins, wherein the use of water during the method is significantly decreased and wherein the intermediate stage of storing and drying the chunk form of the polyolefin
