Patent number: 11746268Abstract: A water- and oil-repellent agent that is an aqueous dispersion containing (A) a fluorine-free polymer having repeating units derived from a fluorine-free (meth)acrylic acid ester monomer, (B) a wax, (C) an aqueous medium, and (D) an emulsifier. The fluorine-free (meth)acrylic acid ester monomer is a compound represented by the formula CH2?CA11-C(?O)—O-A12 where A11 is a hydrogen atom or a methyl group and A12 is a linear or branched C18-30 hydrocarbon group. The emulsifier includes a sorbitan ester and another emulsifier, and the emulsifier has a hydrophilic-lipophilic balance (HLB) of 7.5 to 13.5. Also disclosed is a method of producing the water- and oil-repellent agent and a method of producing a treated substrate by applying the water- and oil-repellent agent to a substrate.Type: GrantFiled: December 20, 2017Date of Patent: September 5, 2023Assignee: DAIKIN INDUSTRIES, LTD.Inventors: Ryousuke Hara, Rumi Kawabe, Masahiro Miyahara, Ikuo Yamamoto

Patent number: 9416486Abstract: Provided is a water and oil repellent composition that provides water and oil repellency that is excellent for base materials such as textile products, and is excellent for preventing adhesion of polymers on rolls during processing. The present invention involves a method for manufacturing a fluorine-containing polymer comprising a first polymer formed from a first monomer, and a second polymer formed from a second monomer. The manufacturing method includes: (I) a step for obtaining the first polymer by polymerizing the first monomer; and (II) a step for obtaining the second polymer by preparing and polymerizing the second monomer in the presence of the first polymer. The first monomer and/or the second monomer includes a fluorine-containing monomer (a), and both the first monomer and the second monomer include a halogenated olefin (b).Type: GrantFiled: July 4, 2013Date of Patent: August 16, 2016Assignees: DAIKIN INDUSTRIES, LTD., NISSIN CHEMICAL INDUSTRY CO., LTDInventors: Ryousuke Hara, Rumi Kawabe, Ikuo Yamamoto, Yuji Gama, Nobuyuki Takahata, Yasuhiro Mitta
