HYDROPHILIC GELS FROM POLYURETHANE-BASED PHOTOINITIATORS Russian patent published in 2016 - IPC C08F2/50 C08G18/48 C08G18/72 C08J3/28 C08J3/75 C08L75/08 

FIELD: chemistry.

SUBSTANCE: invention relates to method for obtaining gel for coating medical devices, gel, obtained thereof and medical device, containing said gel in form of coating. Method includes a) provision of polymer photoinitiator, obtained by combined reaction of (4-(3-(bis(2-hydroxyethyl)amino)propoxy)phenyl)(phenyl)methanone, polyethyleneglycol and 4,4'-methylenebis(cyclohexylisocyanate), followed by b) solidification of matrix by exposure to UV-radiation, and c) exposure of matrix to swelling-inducing medium, with obtaining gel. Stage c) can be realised before or after stage b).

EFFECT: obtaining gels, based on polymer photoinitiators, for obtaining coatings for medical devices.
