Influence of Organoboron Compounds on Ethylene Polymerization Using Cp2ZrCl2/MAO as Catalyst System

open access: yesInternational Journal of Polymer Science, 2014
Organoboron compounds of nonionic and ionic nature, tris(pentafluorophenyl)borane, and N,N-dimethylanilinium tetra(pentafluorophenyl)borate were evaluated to act in conjunction with MAO as activators on ethylene polymerization by using the catalyst ...

Chain-Extended Polyethylene [PDF]

open access: yesPolymer Journal, 1987
The current status of high-strength/high-modulus polyethylene fibres is reviewed with the emphasis on fundamental aspects of ultra-drawing and processability. The drawing mechanism as well as the temperature dependence of the drawability of UHMW-PE (ultra-high-molecular-weight polyethylene) will be discussed.

Velcrand Functionalized Polyethylene [PDF]

open access: yesMolecules, 2019
Velcrands are a specific class of cavitands whose complementary surfaces induce self-dimerization. The insertion of a velcrand as physical cross-linking unit into a polymer is reported. To this purpose, the velcrand was functionalized at the lower rim with an isocyanate group.
