The wide applications of ethylene–propylene copolymers, which range from elastomers to
oligomeric lubricants and additives can be expanded upon controlling the microstructure …

Unbridged oscillatory metallocenes are prone to produce heterogeneous chain
microstructure, for instance, giving rise to elastomeric polypropylene. Here, we use the bis (2 …

Catalysts have a major role in the polymerization of olefins and exert their influence in three
ways:(1) polymerization behaviour, including polymerization activity and kinetics;(2) polymer …

Coordinative chain transfer polymerization (CCTP) has opened a new path for the
development of novel products like olefin block copolymers and chain-end functional …

Two artificial neural network models (forward and inverse) are developed to describe
ethylene/1‐olefin copolymerization with a catalyst having two site types using training and …

Chain shuttling polymerization has provided new pathway for introduction of different
architectures in a single chain. Unlike the commercially available ethylene/1‐octene block …

Abstract (Ind) 2ZrCl2 catalyst was synthesized and used for copolymerization of ethylene
and propylene (EPR) and terpolymerization of ethylene propylene and 5‐ethyldiene‐2 …

Ultra high molecular weight polyolefins as the main category of drag reducing agents play
the main role in energy transportation. The present study seek to thoroughly investigate, the …

PhInd) 2ZrCl2 was synthesized and used for the first time in the terpolymerization of
ethylene, propylene and 5‐ethylidiene‐2‐norbornene (ENB). It showed appropriate activity …

High molecular weight with long linear side branches are frequently used in oil pipelines as
one of the main classes of drag reducer agents (DRAs). We studied the effects of …
