In 1983, DuPont made a significant change in the PE resin, switching from a butene comonomer to an octene comonomer.
Butene is relatively easier to convert than butane, and therefore, researchers pay much attention to the cracking behaviours of butane on various catalysts (Lemonidou and Stambouli, 1998; Ji et al.
In particular, the comparison between the images of LLDPE/ butene and LLDPE/octene extrudates, obtained at an apparent shear rate of 950 [s.
Heritage reports that adding 20% CaCO3, raises extrusion output 22% for hexene copolymer, 39% for octene, and 47% for butene.
In this work, a gas phase butene Ziegler-Natta LLDPE, a solution octene advanced Ziegler-Natta LLDPE, and a solution octene single-site LLDPE were combined to produce mono- and multilayer blown films.
The key raw material costs for Chemtura's butyl- and octyl tin products, including tin ingots, butene, aluminum and magnesium, continue to escalate substantially.

The "linear low" resins were actually copolymers of ethylene and other monomers such as butene, hexane, and octene.
The copolymers of ethylene contain 0-30% by weight of a fraction insoluble in xylene at 25[degrees]C and (23) saturated or unsaturated block copolymers, linear or branched, containing at least one comonomer selected from the group consisting of butadiene, butene, ethylene and neoprene.
