    摘要： A silicon oxide powder can be continuously prepared by feeding a raw material powder mixture containing silicon dioxide powder into a reaction chamber (2) at a temperature of 1,100-1,600° C., to produce a silicon oxide gas, transferring the silicon oxide gas to a deposition chamber (11) through a transfer conduit (10) maintained at a temperature of from higher than 1,000° C. to 1,300° C., causing silicon oxide to deposit on a substrate (13) which is disposed and cooled in the deposition chamber, scraping the silicon oxide deposit, and recovering the deposit in a recovery chamber (18). The method and apparatus is capable of continuous and stable production of amorphous silicon oxide powder of high purity.

    摘要： Provided is a low-cost, highly active, environmentally friendly living radical polymerization catalyst which does not require a radical initiator. An organic compound having an oxidation-reduction capability is used as a catalyst. Even if a radical initiator is not used, a monomer can be subjected to a radical polymerization to obtain a polymer having narrow molecular weight distribution. The cost of the living radical polymerization can be remarkably reduced. It is made possible to prevent adverse effects of using a radical initiator. The present invention is significantly more environmentally friendly and economically excellent than conventional living radical polymerization methods, due to advantages of the catalyst such as low toxicity of the catalyst, low amount of the catalyst necessary, high solubility of the catalyst, mild reaction conditions, and no coloration/no odor (which do not require a post-treatment for a molded article), etc.

    摘要： Provided is a catalyst used for a living radical polymerization method, which contains a central element consisting of carbon and at least one halogen atom binding to the central element. Further, a hydrocarbon compound can be used as a catalyst precursor. A monomer having a radical-reactive unsaturated bond is subjected to a radical polymerization reaction in the presence of the catalyst, consequently a polymer having narrow molecular weight distribution can be obtained, and thus the cost of the living radical polymerization can be remarkably reduced. The present invention is significantly more environmentally friendly and economically excellent than conventional living radical polymerization methods, due to advantages such as low toxicity of the catalyst, low amount of the catalyst used, high solubility of the catalyst, mild reaction conditions, and no coloration/no odor (no need of any post-treatments for a molded article), and the like.

    摘要翻译： 提供了用于活性自由基聚合法的催化剂，其包含由碳和与中心元素结合的至少一个卤素原子组成的中心元素。 此外，可以使用烃化合物作为催化剂前体。 具有自由基反应性不饱和键的单体在催化剂的存在下进行自由基聚合反应，因此可以获得具有窄分子量分布的聚合物，从而可显着降低活性自由基聚合的成本。 本发明由于催化剂的毒性低，催化剂用量少，催化剂溶解性高，反应条件温和，无着色/无色性等优点，比现有的活性自由基聚合法更具环保性和经济性， 无异味（不需要对成形品进行后处理）等。
