Provided are a host-group-containing polymerizable monomer usable as a starting material for producing a macromolecular material with a high degree of freedom in material design, and excellent toughness and strength; a macromolecular material produced using the host-group-containing polymerizable monomer; and a method for producing the macromolecular material. The host-group-containing polymerizable monomer according to the present invention is a host-group-containing polymerizable monomer, and the host group is a monovalent group formed by removing one hydrogen atom or hydroxy group from a cyclodextrin derivative. The cyclodextrin derivative has such a structure that the hydrogen atom of at least one hydroxy group of a cyclodextrin is replaced with a group selected from the group consisting of a hydrocarbon group, an acyl group, and —CONHR wherein R represents a methyl group or an ethyl group.

The presently claimed invention relates to an amine-modified polymer and method for preparation thereof. The presently claimed invention is also directed to the use of the polymer as dispersant in ink and coating compositions.
