Semibatch Emulsion Polymerization of Butyl Acrylate by a Polymerizable Surfactant Stabilized

Pickering Emulsion Polymerization of Styrene-co-butyl Acrylate Nanoparticles by Using Cloisite Na+ as Surfactant

Cloisite Na+was used as a solid surfactant (stabilizer) in Pickering emulsion polymerization of styrene-co-butyl acrylate in presence of oil soluble initiator, azobisisobutyronitrile (AIBN) and water soluble initiator, potassium persulfate (KPS). Fourier transform infrared (FTIR) spectrum approved the corporation of Cloisite Na+ layers within the polymer matrix. Effect of clay content was a...

Model Predictive Control of Free Surfactant Concentration in Emulsion Polymerization

Abstract: In emulsion polymerization processes, the surfactant concentration plays an important role in the latex stability, reaction kinetics and particle size distribution (PSD). Controlling the free surfactant concentration in the aqueous phase ensures the stability of the latex and the control of the micellar nucleation rate. The PSD is determined by particle nucleation, growth and stabilit...

Optimal Temperature Control of Semibatch Polymerization Reactors

B Abstract. Recently, in a paper of Chylla and Haase 2], a model of a multi-product semibatch polymerization reactor has been developed which is representative of those found in the speciality chemical processing industry. One of the aims in these processes is to keep a certain reaction temperature setpoint, in order to t the quality requirements for the polymer. In the present paper, the optim...
