NOVELTY - The apparatus (10) has first and second material supply units (12,14) for supplying the first and second materials to the reaction unit (18) through a reaction line (L1). The reaction unit has static stirrer (60) for static stirring of the first and second raw materials, so as to produce reaction material. A control unit (22) controls the quantity and temperature of the first and second raw materials supplied to the reaction unit from the first and second material supply units.    USE - Consecutive-reaction apparatus such as continuous polymerization apparatus for producing block copolymer used for magnetic disc, semiconductor integrated circuit, medical field, electrolytic membrane for solid polymer fuel cells, high-value-added adhesive agent, and synthetic rubber.    ADVANTAGE - The reaction apparatus can produce the reaction material easily, so that the productivity can be improved. The size, manufacturing cost, running cost, and maintenance cost of the apparatus can be reduced. The flow volume and temperature of the raw material solutions can be controlled reliably. The mass production of block copolymer can be ensured. The contamination of raw material can be prevented and the corrosion of the apparatus can be suppressed.    DETAILED DESCRIPTION - The heat exchangers (34a,3ab) provided at the first and second raw material supply units, are configured to cool the first and second raw materials respectively. The mass meters (35a,35b) of the first and second raw material supply units, are configured to measure the mass of raw material containers (30a,30b). The control unit is configured to control the operation of first and second material supply units, based on the measured results of the mass meters. An INDEPENDENT CLAIM is included for continuously synthesizing method which involves discharging the reaction material obtained by stirring raw materials (A and B) supplied to the reaction unit. The reaction material discharged downstream from the upstream static stirrer (64) and other raw material are stirred using the downstream static stirrer (66), so as to discharge the obtained reaction material from the downstream static stirrer.
