ABSTRACT:
The invention comprises cyclobutarene ketoanhydride monomers and the process for preparing them, and cyclobutarene ketocarboxy monomers. The monomers can be copolymerized with suitable difunctional monomers and subsequently processed to prepare highly crosslinked structures. The monomers can also be used to endcap oligomers with the cyclobutarene functionality. The endcapped oligomer can subsequently be processed to prepare a highly crosslinked network.
