Patent number: 6838411Abstract: This description addresses a process for the preparation of polyolefins from one or more olefinic monomers comprising combining under polymerization conditions said olefins with the product of combining i) an organometallic catalyst compound and ii) a cocatalyst complex comprising a trialkylsilyl-substituted carbenium cation and a suitable noncoordinating or weakly coordinating anion. These complexes exhibit good solubility in aliphatic solvents such that use in aliphatic solution based polymerization reaction processes can be conducted without the use of aromatic solvents or co-solvents and without the need for slurry means of introduction into chemical reaction environments. High number-average molecular weight polymers and copolymers at high rates of productivity were observed from the use of metallocene catalysts complexes when activated with [(3, 5-(Et3Si)2Ph)3C]+ [(C6F5) B]? and used in a hexane-based solution polymerization.Type: GrantFiled: March 18, 2002Date of Patent: January 4, 2005Assignee: ExxonMobil Chemical Patents Inc.Inventor: Francis C.

Publication number: 20040266964Abstract: Polyolefins, preferably polyethylene, having a density of about 0.86 to about 0.93 g/mL, and having methyl branches and at least branches of two other different lengths of six carbon atoms or less, form heat seals at exceptionally low temperatures, thereby allowing good seals to be formed rapidly. This is advantageous when heat sealing these polyolefins, for example in the form of single or multilayer films.Type: ApplicationFiled: July 16, 2004Publication date: December 30, 2004Inventor: Benjamin Andrew Smillie
