Process for producing a polymer spherical powder, and (meth) spherical powder comprising an acrylic block copolymer

The present invention aims to provide suitable as molding material, a method for producing a polymer spherical powder can be obtained by a simple method of small polymer particles having a particle size close to a true sphere. The excellent powder fluidity, and, safe, yet weather resistance, flexibility, rubber elasticity, low temperature properties, adhesion to a polar resin, texture, moldings of high quality excellent in such appearance, skin agents, coating and to provide a polymer spherical powder capable of forming a like. The present invention is a polymer dissolved in a solvent, water and an aqueous dispersion containing a dispersant, a power P / V per liquid unit volume and heated with stirring at 0.2 kW / m
