A core-shell particle including a core containing a perfluoropolymer and a shell containing a non-fluorine resin, the core having a periphery coated with the non-fluorine resin at a coverage of 90% or more, the perfluoropolymer being a polymer containing a polymerized unit based on a perfluoro monomer in an amount of 90 mol % or more relative to all polymerized units, and the shell having a mass of 50 or less relative to a total mass of the core and the shell of 80. Also disclosed is a method for producing the core-shell particle.

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).

Method for manufacturing fluorine-containing polymer

A vinyl chloride-based resin emulsion obtained by using a vinyl chloride-based polymer emulsion, which is obtained by subjecting a vinyl chloride monomer (B) or a monomer mixture comprising a vinyl chloride monomer (B) and an ethylenically unsaturated group-containing monomer (C) to emulsion polymerization in the presence of (A) a styrene-acrylic acid ester oligomer and/or an acrylic acid ester oligomer, as a seed (D), and subjecting a vinyl chloride monomer (E) or a monomer mixture comprising a vinyl chloride monomer (E) and an ethylenically unsaturated group-containing monomer (F) to emulsion polymerization using the seed (D). This vinyl chloride-based resin emulsion exhibits excellent water resistance, moisture resistance, high gloss and alcohol resistance if used in a water-based ink and exhibits excellent color development properties, water resistance, moisture resistance, color visibility, high gloss and release properties if used in a recording paper.
