Provided are elliptical, needle-shaped, or rod-shaped crosslinked polymer particles in which 5-100 mol% of all repeating units are repeating units derived from an unsaturated monomer having a functional group selected from an epoxy group, a carboxyl group, an amide group, a hydroxy group, an amino group, and a thiol group, wherein (1) the average (LAV) length (L) in a two-dimensional projection diagram obtained by irradiating the particles with light from a direction orthogonal to the longitudinal direction is 0.1-80 µm, (2) the average (DAV) breadth (D) in the two-dimensional projection diagram obtained by irradiating the particles with light from the direction orthogonal to the longitudinal direction is 0.05-40 µm, and (3) the average (PAV) aspect ratio (L/D) calculated from the length (L) and the breadth (D) is 1.5-30.
本发明提供了椭圆形、针状或棒状交联聚合物颗粒,其中所有重复单元的 5-100 mol%是由具有选自环氧基、羧基、酰胺基、羟基、氨基和硫醇基的官能团的不饱和单体衍生的重复单元,其中(1)用光从与纵向正交的方向照射颗粒得到的二维投影图中的平均(LAV)长度(L)为 0.1-80微米,(2)用光从与纵向正交的方向照射颗粒得到的二维投影图中的平均(DAV)宽度(D)为0.05-40微米,(3)根据长度(L)和宽度(D)计算得到的平均(PAV)长宽比(L/D)为1.5-30。
