Title: The Innovations of Toshitsune Yoshikawa
Introduction
Toshitsune Yoshikawa is a notable inventor based in Kawasaki, Japan. He has made significant contributions to the field of thermoplastic resin compositions, holding a total of 5 patents. His work focuses on enhancing the properties of olefin polymers, particularly in flame-retardant applications.
Latest Patents
Yoshikawa's latest patents include a surface whitening preventing flame-retardant olefin polymer composition. This innovative process involves preparing a thermoplastic resin composition by heat-treating a mixture of a thermoplastic resin that substantially contains no olefinic unsaturated carbon-carbon bond and an elastomer with such bonds. The elastomer is selected from a group that includes styrene-butadiene-styrene block copolymer (SBS), styrene-isoprene-styrene block copolymer (SIS), 1,2-polybutadiene rubber, and ethylene-propylene-diene random copolymer (EPDM). The crosslinking agent used in this process is a dihydroaromatic compound or a polymer thereof.
