    摘要: A solid polymerization product is continuously produced from a liquid stock by employing a continuous agitator-mixer type reactor including two parallel shafts rotatable in same direction or in opposite directions, a multiplicity of paddles mounted on each of the shafts, and a barrel with its inner periphery proximate to the outer peripheries of the paddles, said paddles being arranged so that the major axis end of each paddle on one of the shafts is allowed to periodically come close to the minor axis ends of a corresponding paddle on the other shaft, said reactor being such that feed stock is charged from an inlet port provided at one end of the longitudinal of the reactor and polymerization product is discharged from an outlet port provided at the other end, said method of continuous polymerization being characterized in that the rear-side portion of the reactor including the outlet port is raised so that the major axis of the reactor has a slope angle of 1.degree.-10.degree. relative to the horizontal, whereby reaction is allowed to take place in the reactor as installed in such inclined state.
