Poly oxyethylene glycol

Fully modified yams had smooth, all-skin cross sections, a stmcture made up of numerous small crystaUites of cellulose, and filament strengths around 0.4 N/tex (4.5 gf/den). They were generally known as the Super tire yams. Improved Super yams (0.44—0.53 N/tex (5—6 gf/den)) were made by mixing modifiers, and one of the best combiaations was found to be dimethylamine with poly-(oxyethylene) glycol of about 1500 mol wt (25). Ethoxjlated fatty acid amines have now largely replaced dimethylamine because they are easier to handle and cost less. [Pg.349]

Block copolymers of ethylene oxide and propylene oxide, less hydrophilic than poly(oxyethylene) glycol and more reactive than the propylene oxide polymers, were introduced by Wyandotte Chemical (USA) under the trade name Pluronic. [Pg.795]

Nitriles react with alcohols in the presence of hydrochloric acid to form iminoester hydrochlorides, which are hydrolyzed to the esters (Pinner synthesis). Heitz and coworkers [21-23] published several fine papers on the polyazoester synthesis from the reaction of a series of poly(oxyethylene) glycol or poly(oxypropylene) glycol and AIBN in the presence of dry hydrochloric acid at 0-5°C according to Pinner synthesis. Condensation reactions of ACPC and dihydroxy terminated poly(oxy-ethylene) glycol yield polyazoesters [24,25]. [Pg.728]

SANS in combination with contrast variation has been used to study the internal (core-shell) structure of nanoparticles prepared from amphiphilic PLA-poly(oxyethylene) glycol (PLA-PEG) block copolymer assemblies intended for use as nanoparticulate drug carriers. Three copolymers were synthesized with a constant PEG molecular weight of 5 kDa and a deuterated PLA chain of either 3, 15, or 45 kDa and nanoparticles... [Pg.1065]

The molecules were synthesized from 9,10-bis(chloromethyl)anthracene and poly(oxyethylene)glycols under basic conditions. The 9,10-anthraceno-... [Pg.24]

Recently, Hyun et al have revealed that TMC can be polymerized according to the AM mechanism when a poly (oxyethylene) glycol/HCl OEt2 system was used as a cationic initiator. The polymerization of TMC in the presence of HCl OEt2 gave triblock or diblock copolymers composed of... [Pg.261]
