Process for production of crosslinked poly(meth) acrylic acid nitroxide compounds |
摘要 |
The present invention relates to a crosslinked poly(meth)acrylic acid nitroxide compound resulting from crosslinking of a poly(meth)acrylic acid nitroxide compound, and an object of the present invention is to provide a method of inexpensively and easily producing a crosslinked poly(meth)acrylic acid nitroxide compound having a high radical concentration. The present invention is a method of producing a crosslinked poly(meth)acrylic acid nitroxide compound including a repeating unit represented by the general formula (2): (in the formula, R represents a hydrogen atom or a methyl group), comprising a nitroxidation step carried out in a state that a crosslinked poly(meth)acrylic acid imino compound resulting from crosslinking of a poly(meth)acrylic acid imino compound including a repeating unit represented by the general formula (1): (in the formula, R represents the same group as that represented by R in said general formula (2)) is dispersed in water. |
