  • Method for modifying polymer, method for producing modified polymer using the same, and modified polymer
    Patent number: 11407871
    Abstract: The present invention provides a new method by which polymers can be modified. The present invention provides a method for modifying a polymer including the step of: irradiating a reaction system containing a polymer with light to react the reaction system in a presence of a compound radical, wherein the compound radical is a radical containing one element selected from the group consisting of Group 15 elements and Group 16 elements, and a Group 17 element.

  • Method for selectively binding target molecule to polymer molded body and method for producing target molecule-bound polymer molded body using the same
    Patent number: 11326035
    Abstract: The present invention provides a new method for modifying a polymer molded body and binding a target molecule. The method for selectively binding a target molecule to a polymer molded body of the present invention includes: a pretreatment step of irradiating a selected surface of a polymer molded body with light in the presence of a compound radical; and a binding step of reacting a target molecule with the polymer molded body after the pretreatments to bind the target molecule to the selected surface of the polymer molded body, wherein the compound radical is a radical containing one element selected from the group consisting of Group 15 elements and Group 16 elements, and a Group 17 element.
