Inverse emulsion copolymerization of DMDAAC with AM has been investigated by the dilatometer technique using the mixture of Span-80 and Tween-80 as the composite emulsifier and 2,2’-azobis (2-methylpropionconidine) dihydro chloride as the initiator. In inverse emulsion copolymerization, the influences of the concentrations of monomers, emulsifier and initiator and initial temperature on polymerization rate and the intrinsic viscosity of polymer have been examined. Its kinetics can be expressed as,. The overall activation energy for the rate of polymerization was determined with a dilatometer as 20.33 kJ/mol over the temperature range 35-55°C.

The present work describes an ultrasonic assisted in-situ dynamic inverse emulsion polymerization process of aniline (ANI) in the presence of organic palygorskite (OPGS) in toluene. Core-shell structure of electrically conducting polymerized ANI (PANI) combined with OPGS was prepared by utilizing the method. Dodecylbenzenesulfonic acid (DBSA) was used as the dopant and emulsifier. The OPGS was obtained via the chemical reaction of pretreated palygorskite with hexadecyltrimethyl ammonium bromide (HTAB). The prepared PANI/OPGS composite was characterized by FT-IR, UV-Vis, XRD, TGA and SEM. In addition, the conductivity was evaluated at different ANI/OPGS weight ratio. When the ANI/OPGS weight ratio increased to 2:7, the conductivity of the composite still remained at 10 S/m at room temperature. The results demonstrated that ultrasonic assisted dynamic inverse emulsion would be an excellent polymerization technique to increase the conductivity and the polymerization rate.
