Emulsification in Batch-Emulsion Polymerization of Styrene and Vinyl Acetate: A Reaction Calorimetric Study
Dispersion of liquid–liquid systems is commonly applied in industrial processes such as extraction, suspension, and emulsion polymerization. This article describes the influence of the quality of emulsification on the course and outcome of a batch-emulsion polymerization of styrene and vinyl acetate. From visualization experiments and polymerizations in combination with reaction calorimetric st...
متن کاملA Kinetic Study of the Emulsion Polymerization of Vinyl Acetate
This report deals with the chemically and the radiation-initiated emulsion polymerization of vinyl acetate. In experiments with potassium persulphate as initiator and sodium lauryl sulphate (SLS) as emulsifier the rate of polymerization is approximately proportional to the square root of initiator concentration and to the 0.25 power of the number of particles. The number of particles is proport...
متن کاملOnline monitoring of an industrial semi-batch vinyl acetate polymerization reaction by programmable logic controllers
This paper describes a virtual online monitoring of the non-measurable conditions inside a reallife industrial reactor for the production of polyvinyl acetate. These non-measurable conditions are the conversion, the polymerization rate, the viscosity and the solids content. The goal of this paper is to use them for control strategies, which can be implemented and solved in real time on common i...
متن کاملvinyl chloride emulsion polymerization reaction: effect of various formulations
a mixture of sodium lauryl sulfate (sls) as ionic emulsifer and stearyl alcohol as non-ionic emulsifer was employed in a vinyl chloride emulsion polymerization reaction to study the infuence of various interactive parameters involved in the reaction system. it was found that the particle size was dependent on the amount and type of emulsifer. the average particle size of polyv...
متن کاملEmulsion Polymerization of Vinyl Acetate in the Presence of a New Cationic Surfactant
In this study, the emulsion homopolymerization system containing vinyl acetate, potassium persulfate, a new cationic polymeric surfactant and water was studied by the applying semi-continuous emulsion polymerization process. The effects of new polymeric emulsifier on the physicochemical properties of obtained vinyl acetate latexes were investigated depending on vinyl acetate percentage in the p...
