The present invention provides modified polymers which can be crosslinked into chemical hydrogels through cycloaddition reactions. It also discloses methods for preparing hydrogels using click chemistry reactions and hydrogels which can be prepared through such methods. The hydrogels are formed easily under mild conditions even in the presence of chemically sensitive bioactive agents, and they are readily biodegradable due to the presence a of bond which is hydrolysable under physiological conditions in the crosslinks. The hydrogels are suitable in tissue engineering or for the delivery of active compounds in a controlled manner.
