The polymers with hydrophilic moieties typically become soft upon hydration. Here we report an exception to this rule. The modulus was found to increase upon water uptake in polymers in which hydrophilic poly(ethylene glycol) (PEG) segments were incorporated randomly into a chain of hydrophobic segm...
