Title: N-VINYL LACTAM-BASED CROSSLINKED POLYMER, COSMETIC, ABSORBENT AGENT FOR INK, AND ABSORBENT COMPOSITE
Abstract:
The purpose of the present invention is to provide a cross-linked polymer which has excellent liquid absorption capability and which allows sufficient gel crushing. This N-vinyl lactam-based crosslinked polymer is characterized by having structural units derived from N-vinyl lactam-based monomers and structural units derived from triallyl cyanurate, and in that the ratio of the triallyl cyanurate-derived structural units is 0.12-0.48 mol% per 100 mol% of all structural units.
