“…Hence, these two particle nucleation processes can be classified into two regimes as regime‐I (below CMC) and regime‐II (above CMC). Thorough investigations of various aspects of colloidal particles synthesis by emulsion polymerization in both the regime have been carried out both theoretically and experimentally 23–29. However, studies on the crosslinked charged copolymer particles are not reported extensively in the literature 7, 13–16, 30–32.…”

ABSTRACT:We report the synthesis of charged spherical colloidal particles of poly [styrene-(co-2-propene sulfonic acid)] crosslinked with divinylbenzene by emulsion polymerization. The effects of concentration of both the emulsifier and initiator on the polymerization, particle size, and charge density are studied. The particle size is found to be dependent on both the emulsifier and initiator concentration and their power dependencies are different. Below critical micelle concentration (CMC), the particle size varies significantly within a small range of emulsifier concentration. In contrast, particle size decrease is not very pronounced at the heterogeneous (micellar) particle nucleation regime where the emulsifier concentration is well above of the CMC. The power dependencies of the number of particles on surfactant concentration are explained in the light of conversion-time profile of the polymerization. The surface charge density of the colloidal particles also varies with both the emulsifier and initiator concentration. Both the particle size and charge density show an inverse relation with the molecular weight of the polymer.

The effect of free radical desorption is studied by using a mathematical model of particle size distribution in continuous emulsion polymerization. By comparing the theoretical prediction with experimental data, the value of Do for the vinyl acetate (VAc) system is best chosen as 0.19 × 10−7 cm2/h. The effect of radical desorption as well as mean residence time on the absolute particle size distribution, total concentration of polymer particles, conversion, and average number of radicals per polymer particle are analyzed by the model proposed.

Neutron and X-ray Scattering narrow fractions of ceramic particles for use as standards, within the range of 0.1-100 //m, using an X-ray analyzer Sedigraph.Masinde and Hickey (Til) described a method for the preparation of aqueous suspensions of poly (lactic acid) microspheres (4.2 µ ). MISCELLANEOUSPark et al. (Ul) measured the "strength" of particle aggregation by exposing metal oxide samples to a calibrated ultrasonic field and following the change in the particle size distribution. Particle size measurements were used to characterize the granular composition of historical plaster and mortar from the Spilberk Castle in city of Brno, Czech Republic. Ii and co-workers (U3) determined the particle size distribution of aerosols resulting from indoor cooking of scrambled eggs, fried chicken, and soup. The results of this research effort gave median particle diameters of 40, 50, and 30 nm, respectively.
