Latest Patents
Okamura's latest patents include the development of shaped products such as fibers and films composed mainly of polyvinyl. These new polymeric materials are designed to exhibit excellent light and heat resistance. The process for preparing these materials involves adding a water-soluble catalyst and emulsifier to an aqueous solution of an amido-polymer. This mixture undergoes emulsion polymerization with added vinyl chloride, followed by the incorporation of polyvinyl alcohol as a matrix to create a dope that is then coagulated.
Another significant patent involves a method for manufacturing medical articles composed of silicone rubber. These articles are coated with collagen for use in the living body. The manufacturing process includes subjecting the surface of shaped silicone rubber articles to spark discharge, coating the treated surface with an acidic aqueous solution of collagen, and drying it to form a collagen layer. The final step involves irradiating the collagen-coated article with high-energy ionizing radiation in a humid atmosphere, ensuring that the water content of the coated collagen exceeds 20% by weight.
