HTE-based opportunities for mastering olefin polymerization catalysts and processes

, 2019
Chemistry in general is not an exact science. Chemical catalysis, moreover, is a purely kinetic phenomenon. This translates into the fact that discovering and even optimizing a catalyst for a desired application heavily relies on trial-and-error, and ...

Photoinduced Initiation of Olefin Polymerization: Enabling Spatial Control with Light

Polyolefins constitute the majority of plastics produced worldwide. Despite the variety of precatalyst activation mechanisms known in the literature, the development of spatially controlled olefin polymerizations remains relatively unknown. If successful,

Observation of Different Catalytic Activity of Various 1-Olefins during Ethylene/1-Olefin Copolymerization with Homogeneous Metallocene Catalysts

Molecules, 2011
This research aimed to investigate the copolymerization of ethylene and various 1-olefins. The comonomer lengths were varied from 1-hexene (1-C6) up to 1-octadecene (1-C18) in order to study the effect of comonomer chain length on the activity and ...
