Abstract:
Particles of an acrylic polymer comprising a constituent unit (A) derived from methyl methacrylic acid and a constituent unit (B) derived from a (meth)acrylic acid alkyl ester in which the alkyl group has 2 to 8 carbon atoms, wherein the particles having electrostatic buildup inhibition rate of 90 to 99.9%.

Claim (Index 5):
A process for producing particles of an acrylic polymer comprising a constituent unit (A) derived from methyl methacrylic acid, and a constituent unit (B) derived from a (meth)acrylic acid alkyl ester in which the alkyl group has 2 to 8 carbon atoms, wherein the particles being in a powder-like form, and the particles having electrostatic buildup inhibition rate of 90 to 99.9%, comprising:\n washing the acrylic polymer obtained by suspension polymerization so as to have a sodium element amount of 3.5 to 50 ppm, wherein the electrostatic buildup inhibition rate being determined by a method comprising: measuring volume density (A) of the particles of an acrylic polymer according to JIS K 7365:1999 \u201cPlastics\u2014Method for determination of apparent density of material that can be poured from a specified funnel,\u201d measuring volume density (B) of a mixture obtained by sufficiently mixing the particles of an acrylic polymer and an anti-static agent in an amount of 0.1 g per 100 mL of the particles of an acrylic polymer, and calculating the electrostatic buildup inhibition rate based on the following mathematical equation (1):\n Electrostatic buildup inhibition rate (%)=Volume density ( A )/Volume density ( B )\u00d7100 \u2003\u2003(1).
