Ethylene and 1-hexene were copolymerized by a hafnium salan-type catalyst activated by B(C₆F₅)₃ producing copolymers over a wide range of 1-hexene incorporation. GPC analysis of the resulting copolymers showed a low dispersity index, suggesting

In this communication, we propose a different approach for analyzing linear viscoelastic relaxation data that is more faithful to the underlying physics and naturally accommodates the thermorheological complexity that is observed in glass-forming pol

The super-Arrhenian temperature dependence of the mobility is a key signature of glass-forming polymers, where the mobility can decrease by 10 orders of magnitude or more as the temperature is decreased toward Tg. A fundamental description of the sup

A zirconium amine bis(phenolate) catalyst that is capable of simultaneously producing both oligomers and polymers of 1-hexene was investigated. It was found that the polymer produced has more branching than the commonly encountered poly(1-hexene), su
