Degradable crosslinkers, compositions therefrom, and methods of their preparation and use

摘要

The present invention is directed toward compositions that are chemically different after application to a substrate as compared to the composition prior to its application. A method of the invention comprises a method of transitioning a crosslinked polymer composition from a first chemical state to a second chemical state. Advantageously, compositions of the invention are relatively stable after transformation to their altered, or second, chemical state.
