Abstract:
The present invention relates to monodisperse hydrogel particles containing a cross-linked product of a vinyl alcohol-based polymer having an ethylenically unsaturated group and an average degree of polymerization of 450 or more, the monodisperse hydrogel particles having an average particle size of 10 to 5,000 μm, and a coefficient of variation of a particle size distribution of 10% or less.
