In the manufacturing method, the complete mixing time in the tank reactor (0M[hr]), the half-life of the radical polymerization initiator at the temperature inside the tank reactor (Ti/2[hr]), the stirring power of the tank reactor (P [kW/m ]), v 3 the average residence time of the starting materials in the tank reactor (0[hr]), and the concentration of the radical polymerization initiat - or (I[ppm]) within the starting materials, satisfy 0M>TI/2, and P 0 IXTI/2<4.
