Patent number: 10280263Abstract: The present the invention is directed to a process and the new materials that are biodegradable for medical use, particularly for drug delivery, therapeutic devices and gene therapy/delivery. The invention illustrates a method of producing a degradable material using polymers made from thiol compounds and alkene/alkyene compounds, wherein one of these compounds contains one or more anhydride groups; and using a thiol-ene step-growth polymerization process, initiated by a free radical initiator. The polymerization process is initiated through photochemical, redox or thermal means, or any combination thereof.Type: GrantFiled: March 25, 2010Date of Patent: May 7, 2019Assignee: CLARKSON UNIVERSITYInventor: Devon A. Shipp
