Resorbable complex shape memory poly(propylene fumarate) star scaffolds for 4D printing applications
Patent number: 11987668Abstract: In one or more embodiments, the present invention provides am method of making a poly(propylene fumarate-co-succinate) (PPFS) copolymer containing a random incorporation of succinate groups and targetable reduction profiles without the need for three or more monomer units. To achieve this, a time-dependent sonication-promoted zinc/acetic acid reduction of the PPM unsaturated double bonds has been used to create a random PPMS copolymer which may be isomerized into the PPFS equivalent. By changing the sonication time as well as the ratios of acetic acid, zinc, and PPM unsaturated alkenes, partial reduction of the PPM alkenes has been shown to give PPMS products containing varying compositions of succinic and maleate units, which may then be isomerized to the PPFS product.Type: GrantFiled: July 15, 2021Date of Patent: May 21, 2024Assignee: The University of AkronInventors: Matthew Becker, Garrett Fredric Bass -
