A Simple Technique for Measuring Particle Size Distributions during Suspension Polymerization

Dynamic Evolution of Droplet/Particle Size Distribution in Suspension Polymerization of Styrene

the effects of temperature, initiator and stabilizer on polymer particle size in suspension polymerization of styrene

in suspension polymerization, particle size distribution of polymer is the outcome of dynamic equilibrium between the break up and coalescence phenomena. the rates of break up and coalescence and consequently polymerization stability depend on several parameters, the most important of which are type and concentration of stabilizer. in this study, the effects of type and concentration of stabili...

Measurement of particle size distribution in suspension polymerization using in situ laser backscattering

Many methods have been developed for characterizing the particle size distribution (PSD) in a suspension polymerization reactor, but are restricted to suspensions with low volume fractions of polymer or to determining the PSD only at the end of the batch. Laser backscattering can be used to measure the chord length distribution for slurries with high particle densities. Here, a combination of i...

Polyvinyl alcohol particle size and suspension characteristics.

PURPOSE To evaluate the size and shape of commercially available polyvinyl alcohol (PVA) particles and to determine whether they change in size when suspended in nonionic contrast and in a solution of nonionic contrast and absolute alcohol. METHODS The two-dimensional area and the long and short axis of PVA particles from several different vendors were measured using a light microscope attach...

to control bead size distribution in suspension polymerization

suspension polymerization processes are significantly important in polymer bead formation. one of the important factors for bead size control in these processes is variation in surface tension. in this research, the prediction of optimum concentration of a surface active agent was investigated on the basis of the experimental surface tension diagrams. the experimental data show that the desired...
