Compared with the conventionalemulsion polymerization system in the presence of sodium dodecyl benzene sulfonate, the latices prepared by emulsifier-free emulsion polymerization have much more narrow distribution of latex particle sizes (0.2um in diameter), better resistance to electrolytes, pH, freeze-thaw, and better mechanical stability. Not only the tensile strength of the copolymers prepared by this method is obviously increased, but also the water resistance and adhesion capacity are significantly enhanced. On the other hand, the TG results indicate the copolymer has lower thermal stability than conventional copolymer.
