Implant manufactured from linear high-density polyethylene.

For instance, copolymers with short chain branching such as linear low-density polyethylene (a copolymer of ethylene and a higher alkene such as hexene or octene) require the use of Analytical Temperature Rising Elution Fractionation (ATREF) techniques.

In fact, preventing branching to produce linear polyethylene requires special methods.

A close approximation to these conditions has been attained by Mandelkern, who annealed a linear polyethylene for 40 days.

Polytanks - plastic polyethylene cisterns, underground water tanks, above ground water tanks, are usually made of linear polyethylene suitable as a potable water storage tank, provided in white, black or green, approved by NSF and made of FDA approved materials.

That is, in fact, what happened with linear low-density polyethylene, a product whose unglamorous name belies the excitement it engendered when it was introduced 20 years ago.

In linear polyethylene, for example, the molecular weight may be as high as 1 000 000, that is, the chain consists of some 70 000 CH2 repeat units.

Examples include purely linear polyethylene, alternating and block copolymers of ethylene with various other vinyl monomers, chiral polymers and polymers with embedded amino acids.

The pole is said to be projected to produce 770 million pounds per year of renewable LLDPE (linear low-density polyethylene), will begin construction in 2008, and is slated to start production in 2011.

For example, highly linear polyethylene can form platelet-like single crystals with a thickness on the order 10-20 nm when crystallized from a dilute solution.
