The previous post described the work of Liebler [1] who showed both epoxy carboxylic acid networks and epoxy anhydride networks contained covalent adaptive networks that underwent transesterification reactions at elevated temperatures (i.e. vitrimers). The unique discovery in both epoxy systems was the viscoelastic behavior at elevated temperatures.  Vitrimers are covalently bonded crosslinked networks.  These networks […] The post Thermoset Re-use and Recycling – Part Four appeared first on Pol
