The present invention relates to methods for preparing a degradable polymer network. The methods for preparing a degradable polymer network comprise a) preparing a polymer composition comprising monomers of cyclic carbonates and/or cyclic esters and/or linear carbonates and/or linear esters and/or cyclic ethers and/or linear hydroxycarboxylic acids at a temperature between 20°C and 200 °C b) adding a cross linking reagent comprising at least one double or triple C C bond and/or a cross linking radical initiator c) processing the polymer composition (that contains the crosslinking reagentj into a desired shape d) Crosslinking by irradiating the mixture. Further the present invention relates to a degradable polymer network. Furthermore the present invention relates to the use of the degradable polymer network.
