摘要:
Disclosed is a polymer powder having an average particle diameter of 20 µm to 300 µm, with a particle diameter of less than 10 µm of 10 mass% or less, and a particle diameter of greater than 300 µm of 10 mass% or less. Further, disclosed is a method for preparing a polymer powder, comprising: forming a melt of a polymer; introducing a supercritical fluid into the melt of the polymer to form a mixed composition; and spraying the mixed composition to prepare the polymer powder.
摘要:
A particulate water absorbent resin is obtained by polymerizing an unsaturated monomer so as to form a cross-linked polymer hydrogel and drying and pulverizing the cross-linked polymer hydrogel, and plural classification steps different from each other are carried out so as to remove fine powder. In this manner, the present invention provides the method for classification of particulate water absorbent resin which method allows particulate water absorbent resin having a desired particle diameter range to be efficiently obtained at low cost while securing the high productivity even in case where a larger production equipment is used.
