,SCHLEICHER ANDREAS DR. 被引量: 8 摘要: A process for the oxidation of a thioether group-containing polymer in which the polymer in solid form is oxidised using ozone in a suspension medium. The polymer obtained is suitable for the production of functional parts subjected to high stresses....
In view of the similarity of the polyethylene molecule to those of n-hexadecane and n-paraffin this value must then also be equal to that for polyethylene in bulk. It may be concluded that, within experimental error, semi-ordering ... CAJ Hoeve,MK O'Brien - 《Journal of Polymer Science ...
The possibility of using dimethyl ether (DME) as a fuel in direct oxidation polymer-electrolyte-membrane (PEM) fuel cells is investigated. A mechanism for DME electro-oxidation is proposed based on the results of half-cell experiments using cyclic voltammetry combined with gas-chromatographic (OC)...
depolymerized2h at the90℃was most effective.The Circular Dichroism(CD),Ultraviolet-spectrophotometry(UV)and Infrared spectrometry(IR)confirmed the structure of oligosaccharides were the same as the polysaccharides',indicating that oxidation depolymerˉization could be used to prepare alginate ...
THERMAL OXIDATION OF POLYMER BLENDS CONTAINING AN ANTIOXIDANT Thermal oxidation of blends of polystyrene and poly(vinyl methyl ether) containing a hindered phenol as antioxidant was studied at 110掳C. The incorporatio... KIM, JAE-HA,KWEI, T.K,PEARCE, ELI M - 《Chemical Engineering Communications...
The oxidation behavior of a polymer-derived amorphous silicon carbonitride (SiCN) ceramic was studied at temperature range of 900°–1200°C using fully de... L Bharadwaj,F Yi,L Zhang,... - 《Journal of the American Ceramic Society》 被引量: 98发表: 2010年 Oxidation kinetics of an Amorpho...
In this paper, complementary to Part I published earlier herein, we report and discuss the results of surface treatment, using a dielectric barrier discharge (DBD), on various polymer films, which already contain intrinsically structurally bonded oxygen in their structures prior to treatment. Surface...

A polycarbazole consisting mostly of 3,9 linkages has been synthesized in a DMF solution by coupling 3,6-diiodocarbazole with an activated copper catalyst. Although this polymer cannot be oxidized by I 2, other acceptors such as iodine m... ...
Soluble pectin, polyphenol-protein complex, oxidation polymerimation of phenolics and polymerimation of tannin are responsible for the growing of particles in cloudy apple juice. 总体看来,混浊苹果中可溶性果胶的含量,多酚-蛋白质复合物的形成、酚类的氧化聚合和原花青素的聚合都对悬浮颗粒的尺寸有影响。2...
