摘要： Provided is a liquid set for a droplet discharging apparatus, the liquid set including: Liquid A containing a multi-branched polymer A, the polymer containing, as a backbone, a polyethylene glycol containing at least three branches, the branches containing one or more electrophilic functional groups in at least one of a side chain(s) and an end(s); and Liquid B containing a multi-branched polymer B, the polymer containing, as a backbone, a polyethylene glycol containing at least three branches, the branches containing one or more nucleophilic functional groups in at least one of a side chain(s) and an end(s); the Liquid A and the Liquid B each having a pH of from 5 to 10, and containing the multi-branched polymer at a concentration of from 0.3% by mass to 20% by mass.

摘要： [Problem] To provide a gel which can be produced in a short time, has controlled properties such as modulus and expansion pressure, and has a low polymer concentration. [Solution] A process for producing a polymer gel in which gel-precursor clusters have been crosslinked with one another to form a three-dimensional network structure, characterized by comprising a) a step in which monomer or polymer units that are present in a concentration less than a critical gelation concentration are crosslinked to form the gel-precursor clusters, the gel-precursor clusters having a storage modulus G′ and a loss modulus G″ which satisfy the relationship G′
