Title: Yuji Maeda: Innovator in Thermosetting Resins and Soft Contact Lenses
Introduction
Yuji Maeda is a notable inventor based in Tokyo, Japan. He has made significant contributions to the fields of thermosetting resins and soft contact lenses. With a total of 2 patents, his work has had a considerable impact on material science and optical technology.
Latest Patents
One of Maeda's latest patents is a novel thermosetting resin composition. This composition comprises at least one [(2,3-epoxypropoxy)alkyl]trialkoxysilane and various polymers, prepolymers, copolymers, and coprepolymers of epoxy-group-containing vinyl monomers. The composition is cured by heating with the addition of a ring-opening polymerization catalyst. It remarkably improves surface hardness, abrasion resistance, weathering resistance, chemical resistances, and heat resistances of acrylic resins and other plastic materials without impairing their inherent transparency and optical properties.
Another significant patent involves the development of soft contact lenses. These lenses comprise a copolymer made from specific monomers, resulting in a product that is soft and flexible in its non-swollen state. The lenses are tougher and less susceptible to microbiological contamination compared to previously known soft contact lenses. The innovative process for preparing these lenses includes cast-polymerizing a mixture of monomers and shaping the copolymer body into lens form in a cooled rigid state.
