Abstract : A new latex particle containing polytetrafluoroethylene and polyarylate in one and the same particle were prepared by a swelling emulsion polymerization process ,in which the initial PTFE particles were first swollen by several acrylates m and then the polymerization was carried out. The composite emulsion was characterized. The formation and morphological o variation of the particles were studied. Furthermore ,the rheologic performance and filmforming of the emulsion were inspected.
