The invention is related to a class of hydrophilic polymers each comprising one sole thiol-containing terminal group. The hydrophilic polymers are highly reactive towards azetidinium groups of an azetidinium-containing polymer upon heating and can find particular use in for producing water-soluble highly-branched hydrophilic polymeric material useful for producing water gradient contact lenses.

A material having a first non-zero elastic modulus capable of reversibly changing the first non-zero elastic modulus to a second non-zero elastic modulus in response to a redox reaction occurring in the material. A method of producing a material that is reversibly cyclable between a first non-zero elastic modulus and a second non-zero elastic modulus, comprising: preparing a polymer comprising both crosslinks that do not depend on metal binding and functional groups capable of having oxidation-state specific binding constants to a metal ion; and doping the polymer with a solution containing the metal ion.
