1. A polymerization reactor for production of a super absorbent polymer, the reactor comprising:
a composition supply part configured to supply a monomer composition solution;
a central pipe connected to the composition supply part and located so as to correspond to a center of the water storage tank;
a composition distribution part including a water storage tank located at a discharge port of the central pipe, a distribution pipe connected to the water storage tank, and an ultrasonic device installed inside the water storage tank;
a conveyor belt located under the composition distribution part and on which the composition solution is dropped; and
an energy supply part for supplying polymerization energy to the composition solution on the conveyor belt,
wherein the ultrasonic device supplies bubbles to the composition solution flowing into the water storage tank,
wherein the distribution pipe is inclined to a side wall of the water storage tank.
