Title: The Innovative Contributions of Takashi Motoki
Introduction
Takashi Motoki is a notable inventor based in Akashi, Japan. He is recognized for his significant contributions to the field of polymer chemistry, particularly in the development of weather-resistant and impact-resistant resins. His innovative approach has led to advancements in materials that are essential for various applications.
Latest Patents
Motoki holds a patent for a process for the preparation of weather-resistant and impact-resistant resins. This two-stage emulsion polymerization process is designed to create resins that exhibit both weather resistance and impact resistance. In the first step, 100 to 80% by weight of an alkyl acrylate with 2 to 8 carbon atoms is copolymerized, along with a vinylidene group monomer and a cross-linking monomer. This results in an aqueous dispersion of a cross-linked copolymer with a degree of swelling above 10, gel content above 80%, and an average particle size of 0.15 to 0.5 microns. The second step involves polymerizing 5 to 50 parts by weight of the solid copolymer from the first step in the presence of 50 to 95 parts by weight of a monomer mixture, which includes at least 50% by weight of an aromatic vinyl monomer.
