Title: The Innovations of Shinichi Kimizuka
Introduction
Shinichi Kimizuka is a notable inventor based in Ichihara, Japan. He has made significant contributions to the field of polymer chemistry, holding a total of 7 patents. His work primarily focuses on the development of innovative polyol compositions and polyurethanes.
Latest Patents
One of his latest patents is a polyol composition that includes a polyol with a polyester chain. This composition is unique as it substantially contains no metal-based polymerization catalyst, and the phosphorus element derived from the polymerization catalyst is maintained at a specific range of 1 to 1000 ppm. Additionally, he has developed a method for producing this polyol composition, which involves reacting a compound with active hydrogen with another compound containing carboxyl, ester, or acid halide groups, all without using a metal-based polymerization catalyst. Another significant patent involves the creation of a polyurethane by reacting a hydroxyl-terminated polybutadiene with a lactone compound, such as ε-caprolactone, to form a polymer polyol. This polymer is then reacted with an unsymmetric diisocyanate to produce a urethane prepolymer, which is further reacted with a chain extender to yield a polyurethane.
