Abstract: Provided is a bioresorbable stent including a stent substrate including a bioresorbable polymer and a contrast medium containing an iodine component, coated on the stent substrate. Since the stent according to the present invention is absorbed in and removed from the human body after a predetermined time, it has excellent biodegradability since it has improved radiopacity by iodine contrast medium coating, it has a high radiography contrast and is very efficient even when a procedure is performed with real time radiography, and since it has low foreshortening and high flexibility, radial force, and re-coil, it may be useful for insertion into a blood vessel having a small diameter, an acute occlusive lesion, an imminent occlusive lesion, and the like.

Abstract: The present disclosure relates to a method of producing polyethylene. More particularly, the present disclosure relates to a method of producing polyethylene capable of reducing wax produced after polymerization by washing a catalyst used in polymerization of ethylene under optimal conditions.

Abstract: Provided is a method for manufacturing a molded plastic products having copper-based compound particulates. The method includes the steps of: reacting copper sulfate with sulfuric salt, at a molar ratio of 1:1 in an aqueous solution at a temperature of 10˜80° C., thereby synthesizing copper sulfide particulates; forming a sheet comprising the copper sulfide particulates dispersed in a thermoplastic resin.

Abstract: Molded plastic products having fine particles of copper-based compound with relatively low price, simple process and good economic feasibility and productivity, and method of manufacturing the products are provided. A chemical structure of the molded plastic products is CuxMy, wherein M is any one selected from groups 15 to 17 of the periodic table, x/y is 0.5-1.5. Also the molded plastic products comprises thermoplastic resin which contains dispersed therein copper-based particles reacts copper sulfate with any one salt, selected from among sulfuric salt, hydrofluoric salt and hydrochloric salt, at a molar ratio of 1:1 in an aqueous solution at a temperature of 10˜80° C.
