Patent number: 9018325Abstract: A nonmetallic compound having an ionic bond with a halide ion is used as a catalyst for living radical polymerization. Even if a radical initiator is not used, a monomer can be subjected to a radical polymerization to obtain a polymer having narrow molecular weight distribution. The cost of the living radical polymerization can be remarkably reduced, and it is made possible to prevent adverse effects of using a radical initiator (such as side reactions). The present invention is significantly more environmentally friendly and economically excellent than conventional living radical polymerization methods, due to advantages such as low toxicity of the catalyst, low amount of the catalyst necessary, high solubility of the catalyst, mild reaction conditions, and no coloration/no odor, etc. The catalyst can be applied to various monomers and enables synthesis of high molecular weight polymers.Type: GrantFiled: August 24, 2012Date of Patent: April 28, 2015Assignee: Kyoto UniversityInventors: Atsushi Goto, Hironori Kaji

Publication number: 20110041912Abstract: The present invention provides phosphonium ionic liquids (11) and coatings made therefrom. Highly fluorinated phosphonium ionic liquids based on (11) having been produced exhibiting high thermal stabilities, low melting points and temperature dependent solvent miscibilities. These salts and derivatives of (11) have also been employed in the preparation of superhydrophobic surfaces, indicating that ionic liquids are not only new alternative solvents, but also viable functional materials. All derivatives of (11) form biphasic systems with common laboratory solvents of ranging polarity at room temperature. Based on the solvent miscibility experiments with water and the high fluorine loading, the PILs showed obvious evidence of being hydrophobic. Coatings made with these phosphonium ionic liquids (11), salts and derivatives thereof were superhydrophobic with water contact angles were measured and all of the surfaces were determined to be superhydrophobic with contact angles >150°.Type: ApplicationFiled: January 28, 2009Publication date: February 24, 2011Applicant: THE UNIVERSITY OF WESTERN ONTARIOInventors: Paul J. Ragogna, Jocelyn J. Tindale
