The application of electron beam irradiation in polymers blend with natural rubber such as thermoplastic polymers, specialty polymers, and thermoset polymers are discussed in this paper for the aspects of physical, mechanical, and thermal properties. The interaction of additives and irradiation for natural rubber blends were also been analyzed. The addition of cross-linking agent such as trimetylolpropane trimethacrylate with appropriate amount could enhance the mechanical properties of the polymer–natural rubber blend and lower the optimum dose of electron beam irradiation. In short, electron beam is another potential aspect worth for study in natural rubber research area. 相似文献

The investigation of a new moderate water shutoff agent: Cationic polymer and anionic polymer 下载免费PDF全文
Cationic polymers and anionic polymers were selected as a moderate water shutoff agent for water production control. Due to the adsorption of polymers on the sand surface, the adsorption capacity under static condition, in porous media, and adsorption morphology on mica were investigated through starch–cadmium iodide method, core flow test, and atomic force microscopy measurement. The adsorption quantity on the sand surface increased with the high polymer concentrations and long adsorption time. With the increase of temperature and shearing time, the adsorption capacity slightly decreased. In addition, the adsorption capacity under water wettability condition was significantly larger than that under oil wettability condition. Alternate injection of cationic polymer and anionic polymer caused larger adsorption capacity in the core test. An adsorption multilayer was formed through alternate adsorption of cationic polymer and anionic polymer confirmed by atomic force microscopy. The visual simulation experiment was also conducted to illustrate adsorption and enhanced oil recovery mechanism. The polymers preferentially entered the high permeability zone and adsorbed on the sand surface, thus enhanced oil recovery. Furthermore, alternate injection of cationic and anionic polymers as a moderate water shutoff agent was successfully applied for water production control in oilfield test. © 2013 Wiley Periodicals, Inc.

About 100 polyolefin-modified mixes were made in pure bitumen or with tall oil pitch as a dispersing agent. The components were mixed directly or by first making a polymer substrate in a dispersing agent. The state of the polymer was determined by examining the residue remaining after toluene leaching. The structures of samples resulting from phase separation during slow cooling were studied using mainly polarization microscopy. The polymers tend to separate as small scales, thin streaks and larger particles. Tall oil pitch makes mixes somewhat more homogeneous, but it increases polymer miscibility only slightly and is not able to stabilize mixes. 相似文献
