摘要： The present invention provides an improved process whereby the thermal stabilization of acrylic fibers is accelerated. The process comprises providing a zone of electron radiation and continuously passing a continuous length of acrylic fibrous material through the zone so as to provide an energy absorption of from about 5 to about 30 megarads. The residence time of the acrylic fibrous material in the zone of electron radiation is less than five seconds. The continuous length of acrylic fibrous material is subsequently continuously passed through a thermal stabilization zone wherein the acrylic fibrous material is heated in an oxygen-containing atmosphere provided at a temperature in the range of about 220.degree. C. to 310.degree. C. for about 10 to 30 minutes. The acrylic fibrous material formed thereby is thermally stabilized (i.e., black in appearance, retains its original fibrous configuration substantially intact, and is non-burning when subjected to an ordinary match flame). The electron radiation treatment has surprisingly been found to accelerate the desired thermal stabilization when compared to prior art processes which do not include the treatment of acrylic fibrous material by electron radiation.
摘要翻译：本发明提供了改进丙烯酸纤维的热稳定化加工方法。该方法包括提供电子辐射区域并连续地使连续长度的丙烯酸纤维材料通过该区域，以提供约5至约30兆拉德的能量吸收。丙烯酸纤维材料在电子辐射区域的停留时间少于5秒。丙烯酸纤维材料的连续长度随后连续通过热稳定区，其中将丙烯酸纤维材料在约220℃至310℃的温度范围内提供的含氧气氛中加热约10分钟至30分钟。由此形成的丙烯酸类纤维材料是热稳定的（即，外观为黑色，保持其原始的纤维状态基本上完整，并且在经受普通火焰时不燃）。与不包括通过电子辐射处理丙烯酸纤维材料的现有技术方法相比，发现电子辐射处理令人惊奇地加速了所需的热稳定性。

摘要： A method for treatment of an organic material containing art object, such as a wood carving, a painting on wood or canvas, a textile hanging or a tooled leather saddle, for preservation and restoration thereof. The method includes the steps of partially impregnating the art object with an unsaturated resin and exposing the partially impregnated art object to a large dose of radiation to polymerize the resin, without addition of any catalysts and without the production of any significant exothermic reaction. The polymerized resin strengthens the art object and the radiation sterilizes the art object, destroying insects, molds, and other destructive biological vectors.

摘要： A filamented polymer material of standard compounding, originally extruded or vertically drawn to a uniform diameter and having typical strength and resiliency characteristics, is converted to a material having increased resiliency characteristics simulating those of catgut and lamb gut for use in tennis racquets. The method for the conversion comprises subjecting a filament or a plurality of twisted together filaments of the material to irradiation, which causes a crosslinking of its molecules.

摘要： String of polyamide is irradiated with dosages of 10.sup.4 to 10.sup.10 rads. It has been discovered by actual experience that in string which is treated in this way the cross linkage of the molecules is enhanced. Such string has higher elasticity and substantially lower damping when set into oscillation than untreated string and that a tennis racket produced with such string is superior to a racket with untreated polyamide string. The dosage is not so high as to cause the string to become brittle.

摘要： The present disclosure generally provides methods and apparatus for efficiently crosslinking silicon carbide fiber precursor polymers with electron beam radiation. The methods and apparatus utilize a platform containing silicon carbide fiber precursor polymer. The temperature of the platform is regulated while the silicon carbide fiber precursor polymer is irradiated to thereby regulate the temperature of the irradiated silicon carbide fiber precursor polymer thereon. In this way, the temperature of the irradiated silicon carbide fiber precursor polymer is regulated via the platform both during and after it is subjected to radiation. At least one of the platform and the e-beam radiation mechanism may be translated with respect to the other to irradiate different portions of the silicon carbide fiber precursor polymer and, ultimately, the entirety of the silicon carbide fiber precursor polymer contained on the platform.

摘要： A powder-based adsorbent and a related method of manufacture are provided. The powder-based adsorbent includes polymer powder with grafted side chains and an increased surface area per unit weight to increase the adsorption of dissolved metals, for example uranium, from aqueous solutions. A method for forming the powder-based adsorbent includes irradiating polymer powder, grafting with polymerizable reactive monomers, reacting with hydroxylamine, and conditioning with an alkaline solution. Powder-based adsorbents formed according to the present method demonstrated a significantly improved uranium adsorption capacity per unit weight over existing adsorbents.
