Tailoring supported olefin polymerisation catalysts using non-equilibrium plasmas [PDF]

open access: yes, 1999
Supported olefin polymerisation catalysts are used to produce more than 20 million tonnes of polyethylene a year. In this thesis, the application of non- equilibrium plasmas to Phillips, Ziegler-Natta, and metallocene catalysts is described. A Cr(acetate)

Comparison of Support Effects on Phillips and Metallocene Catalysts

open access: yes, 2021
Both metallocene and Phillips chromium catalysts are used in the commercial manufacture of polyethylene. Unlike most other commercial metallocene systems, the Chevron Phillips Chemical (CPC) platform does not use methylaluminoxane or fluoroorganic ...

Insights into the activation of silica-supported metallocene olefin polymerization catalysts by methylaluminoxane

open access: yes, 2019
Metallocene-based olefin polymerization catalysts often require large excesses of co-catalyst for optimal catalyst activation. In this work, mechanistic insights into the activation of supported metallocenes by methylaluminoxane as co-catalyst are ...

Impact of Commercial Polyolefin Architecture and Composition on Its Ability to Compatibilize High‐Density Polyethylene/Isotactic Polypropylene Blends

open access: yesJournal of Polymer Science, EarlyView.
This research elucidates the relationship between the molecular structure of commercially available ethylene–propylene copolymers and an ethylene/1‐olefin copolymer and its ability to compatibilize high‐density polyethylene/isotactic polypropylene blends. These findings indicate that the compatibilization of these blends with random copolymers benefits

Near‐Armchair‐Enriched Growth of Single‐Walled Carbon Nanotubes via W‐Containing Fe‐Based Catalyst Systems in Mist FC‐CVD

open access: yesSmall, EarlyView.
A mist‐based floating catalyst chemical vapor deposition (mist FC‐CVD) strategy allows the use of non‐volatile precursors and multi‐component catalyst delivery in a continuous process. Through catalyst composition control, it generates near‐armchair‐enriched single‐walled carbon nanotubes (SWCNTs) and uncovers key factors governing chiral‐angle ...
