Abstract: The morphology of latex particles of acrylic acid/butyl acrylate/styrene copolymer emulsion have been examined by transmission electron microscopy (TEM).The effect of copolymer composition, flexible segment and acidity adjusted with aqueous ammonia of the systems on the morphology of latex particles has been discussed.The morphology of soft latex particles was observed successfully by TEMafter using phosphotungstic acid (PTA) served as support and a negative stain.In an usual condition, the state of film-forming copolymer existence was supposed.
