Abstract
Embodiments of the disclosure generally provide compositions and methods related to oligomeric and polymeric urethane materials that contain hydrolyzable polythioaminal groups for use in biomedical applications.
Claims11
A method of producing a biodegradable urethane material comprising thioaminal groups, comprising:
- forming a urethane oligomer or a urethane polymer with functional groups;
- reacting the functional groups with a sulfur compound to produce thiol groups;
- and
- heating and reacting the thiol groups with hexahydrotriazine compounds to produce a biodegradable urethane material comprising thioaminal groups.
