METHOD FOR OBTAINING GRAFTED METHYL METHACRYLATE COPOLYMER ON COLLAGEN Russian patent published in 2022 - IPC A61L2/00 C08H1/00 C01D17/00 

FIELD: material engineering.

SUBSTANCE: present invention relates to the field of obtaining materials with new properties and their application to create new substances based on natural collagen for use in wound coatings and scaffolds for generative medicine. A method for obtaining a grafted methyl methacrylate copolymer on collagen involves the preparation of an emulsion first in an argon current for 12-18 minutes, and then in an argon current for 4.5-5.5 hours, at a temperature of 20-22°C, when irradiated with an LED lamp of visible radiation. Separation of the catalyst after the end of the reaction by centrifugation of the resulting emulsion, separation of volatile components by vacuum drying. The emulsion is distilled water 63.0-64.0; cod collagen 2.5-3.1; methyl methacrylate 32.5-33.0; and catalyst-powder RbTe_1.5W_0.5O₆ - 0.9-1.0 to the total mass of reagents.

EFFECT: simplification of the production of fungus-resistant material by eliminating the stage of introduction of a fungicidal reagent, improving the characteristics of the material by reducing the particles of the fungicidal material.
