In embodiments, branched polyamines may be formed by reacting a branched polyol with a nitroaryl carboxylic acid to form a nitrobenzoyl ester which, in turn, may then be subjected to a hydrogenating step to form the branched polyamine. The resulting branched polyamine may then be reacted with another hydrogel precursor to form a hydrogel.
