Title: Yeonsuk K Roh: Innovator in Polyamide and Polyurethane Technologies
Introduction
Yeonsuk K Roh is a prominent inventor based in Canton, MI (US). He has made significant contributions to the fields of polyamide and polyurethane technologies. With a total of 6 patents, his work has advanced the understanding and application of these materials in various industries.
Latest Patents
One of his latest patents is titled "Process for the preparation of a reinforced polyamide by extrusion." This invention relates to a method for producing a reinforced polyamide (rP) in an extruder. In this process, a first mixture (M1), a second mixture (M2), and a third mixture (M3) are introduced into the extruder. Subsequently, at least one carbon material is added to create a carbon-containing polymerizable mixture (cpM) within the extruder. This mixture is then polymerized and devolatilized to yield the reinforced polyamide (rP). Additionally, the invention encompasses the reinforced polyamide (rP) that can be obtained through this innovative process.
Another notable patent is for a "High-resiliency polyurethane foam." This foam comprises the reaction product of an isocyanate and an isocyanate-reactive component. The isocyanate-reactive component includes a first polyether polyol in an amount greater than about 5 parts by weight and a second polyether polyol in an amount less than about 80 parts by weight. The resulting high-resiliency polyurethane foam exhibits a resilience of approximately 45 to 70% when tested according to ASTM D3574-11. The method for forming this foam involves providing the isocyanate and the isocyanate-reactive component and reacting them together.
