  • Patent number: 7138455
    Abstract: An acrylic polymer powder obtained by coagulating and drying a latex containing acrylic polymer particles, in which acrylic polymer powder, the average particle size of the powder is 5 to 10 ?m, the percentage of void is 70% or less, and the integral void volume on voids having a pore diameter of 1 ?m or more is 0.9 mL/g or less. Acrylic sol obtained using the powder is excellent in storage stability and fluidity. The storage stability and fluidity of the acrylic sol can further be heightened, or it is possible to give different effects (enhancement of mixing properties of the powder with a plasticizer; lowering of the viscosity of the acrylic sol, enhancement of particle destruction resistance; enhancement of the bleed-out resistance, film uniformity and flexibility of moldings obtained from the acrylic sol, formation of smooth film; etc.
