Abstract
The invention aims to provide a crosslinked polymer having an excellent liquid absorption capacity and sufficient gel-pulverizability. The invention relates to a N-vinyl lactam-based crosslinked polymer including: a structural unit derived from a N-vinyl lactam-based monomer; and a structural unit derived from triallyl cyanurate, the N-vinyl lactam-based crosslinked polymer containing the structural unit derived from triallyl cyanurate in a ratio of 0.12 to 0.48 mol % to 100 mol % of all structural units.
