Polyfethylene glycol oxide

Polystyrene is the name of a homopolymer made from the single monomer styrene. When the name of a monomer comprises two or more words, the name should be enclosed in parentheses, as in polyfmethyl methacrylate) or poly(4-bromostyrene) to identify the monomer more clearly. This method can result in several names for a given polymer thus, polyfethylene glycol) , poly(ethylene oxide) , and poly(oxirane) describe the same polymer. Sometimes, the name of a hypothetical monomer is used, as in polyfvinyl alcohol) . Even though a name like polyethylene covers a multitude of materials, the system does provide understandable names when a single monomer is involved in the synthesis of a single polymer. When one monomer can yield more than one polymer, e.g. 1,3-butadiene or acrolein, some sort of stiuctural notation must be used to identify the product, and one is not far from a formal structure-based name. 

Explain what is meant by tbe term glass transition temperature of an organic binder. Polylvinyl alcohol) and polyfethylene glycol) are often used as a binder and plasticizer combination for oxide particles. 

The resulting polymer is called polyfethylene oxide) or polyfethylene glycol). It is sold under the trade name Carbowax and is as an adhesive and a thickening agent.

Polyfethylene terephthalate) 2GT.— The formation of 2GT from the direct interaction of terephthalic acid with ethylene glycol rather than the transesterification process formerly used, has been the subject of several papers. These have dealt with the production of high purity terephthalic acid, the rheological aspects of its processing and analysis of reaction mixtures by gel permeation chromatography. The formation of 2GT and characterization of the derived fibres from the direct interaction of ethylene oxide with terephthalic acid has also been described. ... 

The synthetic methods used to make functional derivatives of polyfethylene oxide) (PEO) and their applications have been extensively reviewed. The first reported stepwise synthesis of individual PEO oligomers,with as many as 186 monomer units,involved Williamson etherifications in which two moles of the monosodium or monopotassium salt of an appropriate oligofoxyethylene glycol) was reacted with one mole of the appropriate dichloride of another oligo(oxyethylene glycol). However, side products were difficult to remove. Unsaturated side...
