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 کاملGeneralized predictive control of based on vinyl acetate polymerization rate
The process of VAC polymerization has the characteristics such as nonlinearity, time-varying, disturbance and time-delay, moreover, it can not be achieve continuous on-line detection of the vinyl acetate polymerization rate. The traditional control strategy can't acquire satisfactory result, so the implicit generalized predictive control (GPC) algorithm is applied in the control of polymerizati...
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 کاملstudy the effects of low level laser diode on no production and healing of diabetic and cortisone acetate and normal wounded sd rats
nitric oxide (no) is a small molecule synthesized by most of mammalian cells with diverse biological activities including vasodilatation, host defense and wound healing. impaired wound healing is a common occurrence among diabetics and patients receiving glucocorticoid therapy. on the other hand the application of laser in biomedical area have been increased. thus, the current studies were desi...
15 صفحه اولSoft-Sensing Modeling Method of Vinyl Acetate Polymerization Rate
In the procedure of polyvinyl alcohol production, it is hardly accurate measuring the Vinyl Acetate (VAC) polymerization rate. To solve this awkward situation, this paper adopt Genetic Algorithm-Back Propagation (GA-BP) Neural Network to fit the nonlinear relation of the variables which derives from the production process by setting the VAC polymerization rate as the master variable and the ini...
