Claim 9:
10. A method of photopolymerization to prepare solid materials from copolymer formulations according to claim 1, comprising the following steps:
dissolving dextran modified with glycidyl methacrylate in DMSO at room temperature to obtain a solution;
adding poly e-caprolactone modified with 2-isocyanatoethyl methacrylate to the solution obtained from the previous step thereby obtaining co-macromonomers;
carrying out a complete dissolution of the co-macromonomers obtained from the previous step and adding a photoinitiator thereby obtaining a formulation;
leaving the formulation to photocrosslink under UV light with a wavelength of 280 nm to obtain a copolymer; and
washing the copolymer with water for a period up to 7 days and then drying under vacuum.
