In this paper,the preparation of nano silica sol was used TEOS hydrolysis. Silica sol was used to compound the SiO2 sol / polyacrylate with acrylate monomer emulsion polymerization, the effect of sol amount and feeding methods of polyacrylate stability and other property of SiO2 / polyacrylate were studied.

Receding horizon control is used to maximize the productivity of emulsion polymerization processes. The control strategy is adapted for controlling multivariable systems. Two process inputs, the monomer flow rate and the reactor temperature, were manipulated in order to optimize process productivity. The controller performance was validated in the presence of modeling errors. c © 2007 Elsevier ...

A novel multivariate model predictive control strategy (LV-MPC) for trajectory tracking and disturbance rejection for batch processes, based on multiway PCA models, is presented. It directly computes the manipulated variable trajectory adjustments over a future horizon using the structure of the PCA model. The advantages and the modest data requirements are illustrated using an emulsion polymer...

Polyoxometalates (POMs) covalently functionalized with methyl methacrylate groups were applied as surfactants in the emulsion polymerization reaction of styrene. Due to the copolymerization of the methyl methacrylate groups and the styrene monomers, the polyoxometalate clusters are covalently grafted onto the surface of polystyrene latex nanoparticles. Such latex particles are fully covered wit...
