A polymerization reactor for production of a super absorbent polymer according to the present disclosure includes: a composition supply part for supplying a monomer composition solution; a central pipe connected to the composition supply part; 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.

Provided is a system and associated method for the degradation of plastic materials. The system includes a body, hopper, conveying system, drive system and a UV light assembly. The associated method includes providing a polymer material into the hopper, providing a solvent into the hopper, activating the drive system, and activating the UV light.

The invention relates to a process for the acylation of a solid material, known as the hydroxylated material, bearing hydroxyl groups (OH), known as reaction-generating hydroxyls, which are accessible and capable of reacting with at least one fatty acid chloride in gaseous form, said hydroxylated material being scrolled through a chamber, known as the acylation chamber, delimiting an internal space under a gaseous atmosphere. The invention also relates to an acylation device for performing said process.
