    摘要： A process for the preparation of polymer compositions which comprises mixing a conductive component with an anionic polymeric latex containing a polymer; adding a cationic surfactant, or flocculant whereby the aggregation of the latex particles and the conductive component particles results; subsequently adding colloidal stabilizer, followed by the addition of a base to obtain a pH of from about 7 to about 12; heating above about the polymer glass transition temperature thereby enabling the severage, or breakage of the formed aggregated particles; further heating above about the polymer glass transition temperature enabling the coalescence of the polymer and conductive component particles; and optionally washing and drying the resulting coalesced product.
