Patent
Method of olefin polymerization utilizing hydrogen pulsing, products made therefrom, and method of hydrogenation
TL;DR: In this paper, the authors describe an olefinear polymerization process in which at least two introductions of hydrogen are made during the polymerization reaction using metallocenes of the general formula (Cp)m TiXn.
Patent
Method of making a homogeneous-heterogenous catalyst system for olefin polymerization
TL;DR: In this article, the authors proposed a method for making a catalyst for the polymerization of any polymer in which separate polymerizations with a homogeneous catalyst and with a heterogeneous catalyst are possible.
Patent

TL;DR: In this paper, the authors describe a method of contacting a flow of metallocene with a stream of propylene using an antifouling agent at or downstream of a point of contact.
Patent
Method for the preparation of metallocene catalysts
Donald G. Campbell,William J. Gauthier,Margaret Elaine Kerr,Margarito Lopez,David J. Rauscher +4 more
TL;DR: In this paper, a process for the preparation of a supported metallocene catalyst incorporating metallocenes and co-catalysts components on a support is described, where a particulate catalyst support material is provided.
Patent
Polyolefin Production with a High Performance Support for a Metallocene Catalyst System
TL;DR: In this paper, the authors describe a metallocene catalyst system and a process for preparing the system, which consists of a support and metallocenes bound substantially throughout the support.
