ANTIMICROBIAL HIGH POLYMER AND ITS PRODUCTION AND ANTIMICROBIAL MATERIAL USING ANTIMICROBIAL HIGH POLYMER AND ITS PRODUCTION

摘要

PURPOSE: To obtain an antimicrobial high polymer having excellent microorganism absorbing ability and antimicrobial performance and soluble in solvents though it is insoluble or sparingly soluble in water. ;CONSTITUTION: An antimicrobial high polymer consisting of a vinyl-based copolymer of the formula (R is H or 1-3C alkyl; Y is H, 1-3C alkyl, benzyl, ether, carboxyl, carboxylic acid ester or aryl; X is halogen). The copolymer is obtained by copolymerizing a vinylpyridine monomer with a monovinyl monomer and then quaternizing a pyridine group of the resultant copolymer with hydrogen halide and a ratio of the both monomers in copolymerization, i.e., a ratio of (n) to (m) in the formula is preferably (10-90) to (90-10), especially (10:90) to (50:50) and the polymerization degree is preferably 300. The antimicrobial high polymer is applied to a substrate in form of a solvent solution or a dispersion and the coated substrate is dried to produce the objective antimicrobial material. As the substrate, a porous body having large surface area or nonwoven fabric is preferably used.;COPYRIGHT: (C)1995,JPO
