ABSTRACT:
A polymer comprising an .alpha.-glycol structure unit ##STR1## and a carboxylic acid-based structure unit ##STR2## provides superior results with respect to dispersibility, a chelating ability and a viscosity-stabilizing effect and is useful as a detergent builder, pigment- and cement-dispersing agents, a hydrogen peroxide stabilizer and a gas barrier agent. This polymer can further comprise the following lactone structure unit. ##STR3## This polymer can be produced by copolymerizing a conjugated diene monomer and a carboxylic acid-based monomer and oxidizing a copolymer obtained.
