SULFO-CONTAINING POLYMERS WITH ITS OWN ANTIVIRAL ACTIVITY Russian patent published in 2017 - IPC C08F120/56 C08F220/56 A61P31/12 A61K31/785 A61K31/795 

FIELD: pharmacology.

SUBSTANCE: invention relates to the high-molecular weight compounds of the medical purpose, more specifically to new synthetical sulfo-containing homo- and copolymers 2-acrylamido-2-methylpropansulfoacid with its own bioactivity that can be used in pharmacology in the capacity of the future-proof antiviral agents or can serve as the basis for the new effective and harmless antiviral medicinal agents and its pharmaceutical forms. The homo- and copolymers 2-acrylamido-2-methylpropansulfoacid of the stated below formula are obtained by the radical heterophase (co)polymerization in the ethanol at 70°C within 24 hours. The homo- and copolymers 2-acrylamido-2-methylpropansulfoacid have the molecular weight MM=(40-70)⋅10³.
