摘要： The present disclosure provides a peroxide-modified polyethylene and related compositions as well as films, sheets, and multilayer structures made therefrom. A film composition is made from or containing a peroxide-modified polyethylene composition made from or containing a peroxide-modified polyethylene made from or containing the reaction products of a polyethylene composition made from or containing a first Ziegler-Natta-catalyzed polyethylene and a first amount of an organic peroxide to the second reactor.

摘要： Disclosed is a method for producing polyethylene films which have high resistance to deformation or elongation under loading in tension. The method comprises orienting in the machine direction (MD) a high density polyethylene film at a drawdown ratio effective to give the film an MD tensile strength at yield greater than or equal to 50,000 psi, wherein the HDPE has a density greater than 0.940 g/cm3.

摘要： Catalyst systems and solution olefin polymerization processes using a combination of titanium compounds (e.g. halides) with vanadium compounds (e.g. halides or oxyhalides) with tri-n-octyl aluminum (TNOAL) as a co-catalyst, which provides lower in situ oligomerization of olefins that are incorporated into the homopolymer. This feature provides a higher density homopolymer using TNOAL, which enhances polymer properties such as increased moisture barrier and stiffness. Multi-reactor systems and solution olefin polymerization processes comprising this catalyst system.
