polyethylene

 [pol″e-eth´ĭ-lēn]
polymerized ethylene, (—CH2—CH2—)n, a synthetic plastic material, forms of which have been used in reparative surgery.
polyethylene glycol a polymer of ethylene oxide and water, available in liquid form (polyethylene glycol 300 or 400) or as waxy solids (polyethylene glycol 1540 or 4000), used in various pharmaceutical preparations as a water-soluble ointment base. Polyethylene glycol is also used as a laxative.

polyethylene glycol

n.
Any of a family of high molecular weight liquids and waxes that are condensation polymers of ethylene glycol, are soluble in water and in many organic solvents, and are used in detergents, cosmetics, and pharmaceuticals and as emulsifiers, lubricants, and plasticizers.

Synthesis and Characterization of Thermally Stable Organic Composites of Polyaniline with Polyethylene Oxide
[11] and Ottewill [12] suggested that the adsorption of polyethylene oxide-polypropylene oxide- polyethylene oxide ABA copolymers (PE/F 103 and PE/F 108) which have the same size anchoring group but different ethylene oxide (EO) chain weights, is larger in molar terms for the polymer with low molecular weight EO chain, and suggested that the higher molecular weight EO chain crowded the surface and prevent further adsorption.
The examples of these polymers are Hypermer B246 (an ABA block copolymer with an A (polyhydroxystearic acid) as stabilizing chain and B (polyethylene oxide) as an anchoring group and OLOA 11000 which is an AB copolymer with A (polyamine polar head group) and B (polyisobutylene) as a stabilizing chain (used in this study).
