Abstract:
The present invention provides a new class of thermosetting ring-opening metathesis polymerization materials based on norbornene and oxanorbornene dicarboximide moieties containing at least one acetal ester group linkage. The acetal ester group is degradable when subjected to heat or acidic aqueous hydrolysis. The polymerization materials can be used in reworkable thermosetting compositions. R1-Rs, X, and n are defined herein.
