US Patent Issued to University of Rochester on April 29 for "Melt-processable shape-memory elastomers containing bisurea segments" (New York Inventor)

ALEXANDRIA, Va., June 9 -- United States Patent no. 12,286,508, issued on April 29, was assigned to University of Rochester (Rochester, N.Y.).

"Melt-processable shape-memory elastomers containing bisurea segments" was invented by Mitchell Anthamatten (Rochester, N.Y.).

According to the abstract* released by the U.S. Patent & Trademark Office: "A shape-memory polymer that is melt-recyclable with high processability and little performance loss, in contrast to known Crosslinked semicrystalline shape-memory networks that are capable of storing large amounts of elastic energy with negligible plastic deformation but as thermosets are not easily melt-processed or recycled. In examples herein, catalyst-free isocyanate chemistry is used to prepare...
