A motor-driven stirrer. That illustrated in Figs. II, 7, 1 (see also Fig. II, 7,1) is quite satisfactory the motor is supported on a stout metal bar fitted across the thermostat tank. 

Model predictions are caipared with experimental data In the case of the ternary system acrylonitrlle-styrene-methyl methacrylate. Ihe experimental runs have been performed with the same recipe, but monomer feed composition. A glass, thermostat ted, well mixed reactor, equipped with an anchor stirrer and four baffles, has been used. The reactor operates under nitrogen atmosphere and a standard degassing procedure is performed Just before each reaction. The same operating conditions have been maintained in all runs tenperature = 50°C, pressure = 1 atm, stirring speed = 500 rpm, initiator (KgSgOg) 0. 395 gr, enulsifier (SLS) r 2.0 gr, deionized water = 600 gr, total amount of monomers = 100 gr.

The electrolyte (the bulk solution) is in the inner of the two chambers, and thermostat fluid circulates in the outer chamber, hi the top of the Avesta cell are mounted the salt bridge from the reference electrode, a thermometer, nitrogen gas inlet, counter electrode, and perhaps a mechanical stirrer.

Polymerizations were carried out in a dried 250 ml three-necked flask equipped with a nitrogen inlet, magnetic stirrer, reflux condenser, dropping funnel, and recording thermocouple. The reaction flask was immersed in a constant temperature bath, 50 ml solution of phenyl isocyanate in acetonitrile (cone. 1 mol kg l) was pipetted into the flask and stirred magnetically while the catalyst solution in acetonitrile (50 ml) was placed in the thermostat-controlled dropping funnel. When constant temperature (+ 0.1oC) was reached in the flask as well as in the funnel, the catalyst solution...
