Abstract
Novel associative acrylic polymers prepared by radical inverse emulsion polymerization. It is a methacrylic ester in which the radical is composed of a hydrophilic segment and of a hydrophobic segment. The associative polymers of the invention can be used as thickeners, flocculating agents or filler-retaining agents.
