Small Science, Volume 6, Issue 10, October 2026.Conductive high‐density poly(ethylene) (HDPE) is introduced as a new material platform for additive manufacturing electrochemistry, expanding the limited polymer feedstocks currently available. A solvent‐free thermal compounding process incorporating 40 wt% carbon black produced a flexible, plasticizer‐free filament with a low bulk resistivity of 16.4 (

The blocky structure of Ziegler-Natta "random" copolymers: Myths and experimental evidence
, 2020 The crystallization behavior of butene-ethylene random isotactic copolymers prepared with a Ziegler-Natta catalyst, in particular the surprising crystallization of form II of isotactic polybutene in samples with a high ethylene concentration, provides ...

Advanced Synthesis &Catalysis, Volume 368, Issue 18, 19 September 2026.A general C─C cross‐coupling method employing earth‐abundant organoaluminium nucleophiles is enabled by electronically highly donating and sterically demanding ylide‐substituted phosphine (YPhos) ligands under Pd catalysis. This protocol represents an organoaluminium cross‐coupling that operates with a single catalyst system across all carbon ...

Impact of Pyridine on the copolymerisation behaviour of a Ziegler-Natta catalyst
, 2021 The aim of the thesis is to study the influence of a Ziegler Natta catalyst poison on the copolymerisation behaviour of ethylene. The catalyst poison of choice is pyridine and the comonomer 1-butene. For statistical analysis, a Design of Experiments (DoE)

Dimerization of 1-butene via zirconium-based Ziegler-Natta catalyst
, 2000 A zirconium-based Ziegler-Natta catalytic system has been tested in the dimerization of 1-butene. It was found that the concentration of Et2AlCl, Ph3P and PhONa as well as the reaction temperature had great influences on the activity and selectivity of ...
