Effect of Multihole Silicon Dioxide on Crystallization Behavior of Poly(ethylene oxide);

This paper introduced advance in synthesis technology of poly(ethylene oxide)and mechanism of coordinate anionic polymerization,and reviewed the catalysts used in the polymerization of ethylene oxide.

2-Sulfanilylpyrimidine(sulfadiazine) sodium was used to initiate the ring-opening polymerization of ethylene oxide to form sodium sulfadiazine poly(ethylene oxide)(PEO) (inhomogeneously), and the polymerization was terminated with 3,5-di-(N-acetamino)-2,4,6-triiodobenzoyl chloride to form a bifunctional PEO with a targeting and a contrast-medium group.

Combined with the GB8574-2002 potassium tetraphenylborate gravimetry method, silicon was deposited by polyethylene oxide in an acid environment.

The results showed that the compound prepared has s high retardation efficiency and high smoke removing property for polyethylene and polyethylene oxide.

The solubility parameters of PEO (polyethylene oxide), PPO(polyepoxypropane) and PTHF (polytetrahydrofuran) have been studied by inverse gas chromatography using Guillet's method.

Conductivity of Polyoxyethylene/Poly (2-vinyl pyridine)Blend and Compatibilizing Effect of Lithium Perchlorate;

Graft terpolymerization of polyoxyethylene macromer with acrylates;

Then multiblock copolymers was obtained by condensing polyoxyethylene and poly(2 vinylpyridine)with dichloromethane in the presence of potassium hydroxide.

Some Improvements in Measuring Silica with the PEO Condensing Weight Method;

In order to improve the electrochromism of V2O5 films, PEO/V2O5 nanocomposite films were prepared by direct intercalation of high ion conducting and water soluble poly(ethylene oxide), PEO, into V2O5 sol via sol-gel route.

This review focuses on recent progress in stimuli-responsive and amphiphilic block copolymers containing polymethacrylates,poly(ethylene oxide)(PEO),and poly(propylene oxide)(PPO),which are prepared by various cont.
