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.

polyethylene glycol

A substance used with other ingredients to be used as a laxative. Brand names are Klean-prep and Movicol.

[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).

Polyethylene oxide (PEO) polymers are high-molecular-weight, water-soluble thermoplastics that have recently found wide use in specialty applications such as lubricious razor strips, pharmaceutical excipients, and water-soluble packaging.
The hardener is prepared by a process comprised of reacting a mixture comprised of at least one epoxidized polyalkylene oxide selected from the group of epoxidized polyethylene oxides, epoxidized polypropylene oxides, epoxidized polyethylene propylene oxides and mixtures thereof; at least one epoxidized aromatic hydroxy compound selected from the group of bisphenol A epoxides, bisphenol F epoxides and mixtures thereof; and at least one aromatic hydroxy compound selected from the group of bisphenol A, bisphenol F and mixtures thereof, to form an intermediate product; and introducing an excess amount of polyamine sufficient for the reaction of one molecule of polyamine with each epoxy group in the intermediate product, and reacting the intermediate product with the polyamine.
