Abstract
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 reagent 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.
