Beschreibung
Zusammenfassung:	An object of the present invention is to provide a polymer particulate material with a low compression modulus and a high recovery rate from compression deformation. The present invention provides a polymer particulate material obtainable by co-polymerizing comonomer components including a polyfunctional (meth)acrylate having a structure represented by the below formulas (1), (2) or (3), and a monofunctional (meth)acrylate monomer having a structure represented by the below formula (4), the polymer particulate material shows a recovery rate from compressive deformation of 70% or higher: In the formula (1), n represents an integer within the range of 4 to 10. In the formula (2), R11 represents a hydrogen atom or a C1-4 alkyl group, R12, R13 and R14 each represent a C1-4 alkylene group, and R15, R16 and R17 each represent a hydrogen atom or a methyl group. In the formula (3), R3, R4, R5 and R6 each represent a C1-4 alkylene group, and R7, R8, R9 and R10 each represent a hydrogen atom or a methyl group. In the formula (4), R1 represents a hydrogen atom or a methyl group, and R2 represents a C5-18 alkyl group.
