| titleOfInvention | Process for producing spherical polymer powder and spherical powder comprising (meth)acrylic block copolymer |
| abstract | The present invention has its object to provide a process for producing spherical polymer powders by which polymer particles close to nearly spheres in shape and small in particle diameter and therefore suited for use as a molding material can be obtained in a simple and easy manner. Furthermore, the present invention also has its object to provide a spherical polymer powder which is excellent in powder flowability and is safe and can form high-quality moldings, coverings, coatings and like products excellent in weather resistance, flexibility, rubber elasticity, low-temperature characteristics, adhesion to polar resins, touch and feel and appearance, among others. The present invention relates to a process for producing spherical polymer powders, which comprises the step of heating an aqueous dispersion comprising a solution of a polymer dissolved in a solvent, water and a dispersant with stirring under conditions such that the power per unit volume of the dispersion, P/V, amounts to at least 0.2 kW/m 3 to thereby remove the solvent from the aqueous dispersion, and a spherical powder comprising a (meth)acrylic block copolymer. |
