Title: Innovations of Yasuyuki Hatakeyama
Introduction
Yasuyuki Hatakeyama is a notable inventor based in Osaka, Japan. He has made significant contributions to the field of polymerization, particularly in the prevention of scale adhesion in polymerization tanks. With a total of seven patents to his name, his work has had a considerable impact on the industry.
Latest Patents
One of his latest patents is a method of preventing scale adhesion to the surfaces of a polymerization tank. In this innovative approach, a specified coating agent is applied to the surfaces that will come into contact with vinyl chloride monomer during the polymerization process. The coating agent is an aqueous solution of a modified condensation product of phenol and aldehyde. The pH of the solution is adjusted so that the product dissolves at ambient temperature upon coating and separates out of the solution when heated on the surfaces. This results in a thin film of the coating agent that adheres strongly to the wall surface, effectively preventing the adhesion of the product polymer.
