A 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...

281e Kinetic Modeling of the Vinyl Chloride Suspension Polymerization

The physical properties of the polymer product determine to a large extent its processability and applications. A large number of properties are directly related to the molecular mass distribution (MMD) of the polymer product. Besides the MMD, the polymer microstructure also plays an important role and influences to a large extent the thermal stability of the polymer product. Most of the therma...

Copolymerization studies of vinyl chloride and vinyl acetate with ethylene using a transition-metal catalyst.

Since the advent of Ziegler-Natta polymerization of ethylene, attempts have been made to extend coordination polymerization to commercially important monomers with polar functionality. In this study we examined the copolymerization of perdeuterated vinyl chloride (VC) and perdeuterated vinyl acetate (VA) with ethylene using a tridentate Fe(II) dichloride pyridine diimine metal catalyst. The res...

Soft-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...

Generalized 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...
