    • The present invention relates to a process for the polymerization of acrylonitrile or a monomer mixture containing acrylonitrile as a main component and at least one other ethylenically unsaturated compound, characterized in that the polymerization is conducted at a temperature above 120.degree. C. under a pressure above the vapor pressure generated in the polymerization system under the polymerization conditions in a system in which water is present in a range of 3 to 50 percent by weight based on the total weight of the monomer(s) and water to produce an acrylonitrile polymer in a substantially molten state. The polymers produced according to the above process have the advantage of being able to be directly shaped by extrusion without the need of solvents.

    • A battery-monitoring circuit includes a bidirectionally current-controllable means disposed between a secondary battery and a charging circuit or a load circuit for monitoring the charge or discharge of the secondary battery to prevent undesirable charging. The current control means has characteristics as an active diode, which is constituted by an error amplifier to which a predetermined voltage and voltage between both terminals of the current control means are supplied. The current control means supplies an output to the current-controllable means, such that the output of the current-controllable means is controlled constant, equal to the predetermined voltage.
