  • Photopolymerized biodegradable copolymer formulations for biomedical applications
    Patent number: 11932719
    Abstract: A biodegradable based polymers for the production of biodegradable medical applications is provided. The biobased material has a copolymer constituted by dextran modified with glycidyl methacrylate and poly (#-caprolactone) modified with 2-isocyanatoethylmethacrylate, which are combined in different formulations and used to produce membranes, 3-D scaffolds and hollow tubes that can be used as biomedical devices for diverse applications, such as drug delivery systems, tissue engineering scaffolds, repair and regeneration of peripheral nerves, among others.

  • PROCESS FOR THE PRODUCTION OF A FORMULATION CONTAINING POLY(LACTIC ACID) AND ALIPHATIC AND/OR AROMATIC POLYESTERS AND PRODUCTS USING IT
    Publication number: 20220204756
    Abstract: The invention presented in this document relates to processes for the preparation of a formulation containing poly(lactic acid) (PLA) and aliphatic and/or aromatic polyesters which plasticize it, and its use in monofilaments and films. The presence of polyesters does not remove the biodegradability and composting characteristics of the raw materials used in the formulation. The invention also concerns products that use the formulation.
