Abstract
Styrene-based copolymers having acid monomer units, dispersions, preparation method and use thereof are provided. The styrene-based copolymer is prepared by polymerizing styrene, one or more acid monomers, and optionally butadiene at a temperature of 40° C. or greater and then is vulcanized. The obtained styrene-based copolymer is used in asphalt-based systems.
