Abstract
There is disclosed a polymer gel including a structure derived from a main monomer M1, a crosslinking agent monomer M2, and a radical polymerization initiator I as a constituent element. In this polymer gel, a monomer reactivity ratio r1 of the main monomer M1 and a monomer reactivity ratio r2 of the crosslinking agent monomer M2 satisfy a condition of r1>r2, a molar ratio of an addition amount of the crosslinking agent monomer to an addition amount of the main monomer M1 is 1% or less, and a decomposition rate (10−7/s) of the radical polymerization initiator I at 25° C. is 25 or more. This polymer gel has properties of high strength and high viscosity.
