Abstract
Described are shape-memory polymers that have a branched or telechelic prepolymer having a low polydispersity crosslinked with a stoichiometric amount of a multifunctional crosslinker. Also described are methods of making shape-memory polymers by crosslinking a stoichiometric amount of a multifunctional crosslinker with a branched or telechelic prepolymer having a low polydispersity. Methods of measuring the energy storage capacity of a shape-memory polymer are also disclosed.
Claims18
A shape-memory polymer comprising:
- a branched or telechelic prepolymer having low polydispersity and crosslinks with a multifunctional crosslinker, wherein the branched or telechelic prepolymer is crosslinked to the multifunctional crosslinker by a Michael addition reaction and wherein substantially none of the crosslinks are the reaction product of a free radical polymerization reaction.
