    摘要: The present invention provides for a method of converting an anionic latex to a cationic latex by the addition of a steric stabilizer and a cationic surfactant. The invention also provides for a method of using the cationic latex prepared by the conversion, in an asphalt emulsion. The converted latex provides improved torsional recovery properties to the cured asphalt emulsion.
