The present invention provides a novel amino-group-containing polymer (salt) and a production process therefor wherein the amino-group-containing polymer (salt) is a product by a process including the step of introducing amino groups into a grafted polymer having a polyether skeleton, and can make good use of the reactivity or cationic property of at least primary amino groups and further, according to circumstances, secondary amino groups, and further can display various performances, such as curability useful for various uses and adsorbency onto films or fibers. The novel amino-group-containing polymer (salt) is a product by a process including the steps of: carrying out a graft polymerization of a monoethylenically unsaturated monomer component onto a polyether compound, wherein the monoethylenically unsaturated monomer component includes an unsaturated carboxylic monomer as an essential component, and wherein the polyether compound has a specific repeating unit in a ratio of not less than 30 mol % and has a number-average molecular weight of not less than 150; and introducing amino groups by carrying out a ring-opening addition of an alkylenimine to at least a part of carboxyl group portions of the monoethylenically unsaturated monomer component which has been graft-polymerized onto the polyether compound, wherein at least a part of the amino groups might be neutralized with an acid.
