摘要： The present invention relates to coated polymer particles comprising a water-swellable polymer core and an essentially continuous coating encapsulating the core. The coating comprises an oxide, hydroxide or oxide hydrate of silicon, aluminum, zirconium, tin or titanium. The polymer particles do not show instantaneous swelling, when contacted with water or a water-containing liquid, but show delayed water absorption after an appropriate period of time. The coated polymer particles may be used in oil fields, in mining, for construction chemical compositions or as carrier for active substances. The coated polymer particles are prepared by a suspension coating process or a fluidized bed coating process.

摘要： Disclosed are a maleimide-α-alkylstyrene-based, heat-resistant bulk tetrapolymer and a preparation process thereof. More specifically, disclosed are a bulk tetrapolymer, comprising 5-60 wt % of an N-substituted maleimide monomer, 10-70 wt % of an α-alkylstyrene monomer, 5-50 wt % of an unsaturated nitrile monomer and 3-50 wt % of an aromatic vinyl monomer, as well as a continuous bulk polymerization process for preparing the same. The disclosed bulk tetrapolymer has a weight-average molecular weight (Mw) of 70,000-300,000 and a glass transition temperature of 150-200° C., shows excellent high-temperature thermal stability and heat resistance and a remarkably low melt viscosity, and thus is excellent not only in processability, but also in productivity, processability, moldability and blendability, when it is blended with other resins. Also, the continuous bulk polymerization process is equipped with a devolatilizer and enables the bulk tetrapolymer to be produced at low cost and high efficiency.

摘要： A quad-polymer composition includes monomers of (a) acrylonitrile, (a) vinylimidazole, (c) methyl acrylate and (d) either acrylic acid or itaconic acid. Such quad- polymer compositions may be used to form fibers (such as by melt spinning) that may then be annealed, stabilized, and/or carbonized to produce carbon fibers. The quad-polymer composition may be used for supercapacitors, lithium battery electrodes once carbonized, and as synthesized, it may be used for wound healing fibers, fabrics, coatings, and films, and anti-bacterial/anti-microbial fibers, fabrics, coatings and films. The carbon fibers formed from the quad-polymer composition may be used for the fiber composites for automobile, aerospace structures, marine structures, military equipment/parts, sporting goods, robotics, furniture, and electronic parts.

摘要： The present invention provides a method for preparing a polyion thin film (in particular a polyion thin film with different surface morphologies) and the polyion thin film prepared by the method. The method comprises: providing a substrate, and coating a first lubricant on a surface of the substrate or on a surface of a tinfoil covered on the surface of the substrate; covering a film-forming liquid of the polyion thin film on the surface of the substrate with the first lubricant, and after coating uniformly, covering a cover plate coated with a second lubricant on the film-forming liquid; performing a polymerization reaction of ionic liquid monomers in the film-forming liquid to form a polyion thin film; and separating the polyion thin film and cleaning it to obtain the polyion thin film. The polyion thin films with different surface morphology can be prepared. The present invention further provides a detection kit.
