New techniques have been developed for the preparation of spongy materials and hydrogels based on triblock copolymers of lactide and ethylene glycol with various molecular structures. The influence of the composition of the initial copolymers and supramolecular structure on their mechanical characteristics and biocompatibility was studied. Cytological studies have shown that all materials have a high level of cell viability (GSP). The possibility of obtaining hydrogels with elastic moduli up to 4460 kPa, a record for such systems, was shown.
