Title:
アクリル-フッ素複合重合体粒子
Document Type and Number:
Japanese Patent JP5229367
Kind Code:
B2
Abstract:
Provided are acryl-fluorine composite polymer particles which are capable of acquiring water resistance even by a forced drying method and which are capable of reducing the amount of fluororesin while still maintaining weather resistance and chemical resistance, and an aqueous coating composition using the particles. That is, there are provided acryl-fluorine composite polymer particles comprising: (A) a vinylidene fluoride polymer containing, as structural units, at least one type of a fluoroolefin unit selected from a group consisting of a tetrafluoroethylene unit, a hexafluoropropylene unit and a chlorotrifluoroethylene unit, and a vinylidene fluoride unit; and (B) a crosslinkable acrylic polymer (B) containing a (meth)acrylic acid ester unit (b1) which is compatible with the vinylidene fluoride polymer (A), a (meth)acrylic acid ester unit (b2) which is incompatible with the vinylidene fluoride polymer (A), and a (meth)acrylic monomer unit (b3) having a crosslinkable group capable of cross-linking by heating. The mass ratio of vinylidene fluoride polymer (A)/crosslinkable acrylic polymer (B) is 10/90 to 90/10.
