Process for making macromolecular networks
The present invention relates to processes for making macromolecular networks, macromolecular networks made by such processes, and methods of using such macromolecular networks. Such process employs a low amount of amine compound as a reaction accelerant. The rates of chemical reaction are thereby easily controlled over several orders of magnitude, permitting efficient catalysis and control of reaction conditions needed to produce thermochemically stable macromolecular networks.
