Abstract: The present invention relates to a monomer with anti-microbial characteristics, a polymeric compound with anti-microbial characteristics using the same, and manufacturing methods thereof, and more particularly, to an antimicrobial monomer comprising a saturated or unsaturated hydrocarbon having a polymerizable functional group within its structure according to formula (1) in which the respective moieties have the meanings defined in the following specification. Also, the present invention provides a polymeric compound using the above antimicrobial monomer, a manufacturing method thereof, and a polymeric resin composition. The compounds according to the present invention have durable antimicrobial activity and high heat resistance, they do not give rise to toxicity when added to conventional resins by not eluting the antimicrobial compounds, and they do not have an effect on the properties of molded products.

Abstract: The present invention relates to an anti-microbial or anti-coagulating polymer resin and a method for preparing the same, and a medical appliance or instrument using the same, and more particularly to a method for preparing an anti-microbial or anti-coagulating medical polymer resin comprising the steps of simply mixing a polymer resin with at least one kind of pharmaceutically active material without using a solvent. The pharmaceutically active material is preferably an anti-microbial or anti-coagulant. According to the present invention, an anti-microbial or anti-coagulating material that is safe to a human body is mixed with a polymer resin by simple addition in an environmentally favorable non-solvent method, thereby maintaining superior anti-microbial effects even after high temperature molding, minimizing a released amount of anti-microbial to increase anti-microbial effect durability, and solving a toxic problem in a body.

Abstract: The nitration of aromatic compounds is achieved in high yield and selectivity by using oxygen activated by an inorganic catalyst and nitrogen dioxide. Since this process uses neither concentration nitric nor sulfuric acids, the generation of spent waste acid does not occur. Furthermore, the process does not encounter the problem of high costs associated with the generation of ozone as in an alternative nitration process. Since the solubility of oxygen in a reaction medium is increased by using pressurized oxygen, nitrogen dioxide is activated by a porous inorganic oxide and thus an aromatic compound(e.g., benzene) is nitrated into a nitro compound (e.g., PhNO2), the reaction rate is significantly increased, and the recovery of reactants is easy due to the insolubility of the catalyst.
