Title:
ACRYL-FLUORINE COMPOSITE POLYMER PARTICLES, AND AQUEOUS DISPERSANT
Document Type and Number:
WIPO Patent Application WO/2012/036297
Kind Code:
A1
Abstract:
Provided are acryl-fluorine composite polymer particles suitable for aqueous fluororesin coatings, which significantly reduce the amount of fluorine, are capable of forming coatings with excellent weather resistance, while significantly reducing costs, and are capable of minimizing reductions in the sheen of obtained coatings. Acryl-fluorine composite polymer particles containing (A) a vinylidene fluoride polymer component containing at least one type of fluoroolefin unit selected from a group comprising a tetrafluoroethylene unit, a hexafluoropropylene unit and a chlorotrifluoroethylene unit as structural units, and a vinylidene fluoride unit, and (B) an acrylic polymer component containing an monomer unit containing an ethylenically unsaturated group having a (meta) acrylic monomer unit and an ultraviolet absorption site, or a monomer unit containing an ethylenically unsaturated group having an optical stabilization site, wherein the content of said vinylidene fluoride polymer component (A) is not more than 50 mass %.
