PURPOSE:To obtain a deodorizing composition, excellent in deodorizing function, hardly coloring fiber and excellent also in washability by copolymerizing a comonomer such as a vinyl nickel salt of sulfonic acid or carboxylic acid with acrylonitrile, etc., in a specific amount in terms of weight of nickel, etc. CONSTITUTION:The objective composition is obtained by copolymerizing a vinyl nickel salt comonomer, vinyl cobalt salt comonomer or vinyl salt comonomer of a sulfonic acid or a carboxylic acid (e.g. allyl sulfonic acid) of >=3000ppm as nickel, cobalt or copper, based on the solid content, with acrylonitrile, etc. |
