Abstract
The polymer compositions described herein include the reaction product obtained from a mixture that includes: (i) a hydroxyl terminated intermediate containing at least one furan functional group; and (ii) a polyisocyanate component. The polymer compositions may further include a polymaleimide compound which may be (a) added as a component of the polymer composition, (b) incorporated into the structure of the hydroxyl terminated intermediate containing at least one furan functional group, or (c) both. The resulting polymer composition is capable of thermally reversible crosslinking. Also described are processes for making such polymer compositions, methods of reversibly increasing and/or decreasing the amount of crosslinking in a polymer composition thermally, through utilization of the Diels-Alder cycloaddition mechanism between furan functional groups and the polymaleimide compound, and methods of using the described furan functional group containing materials to prepare polymer compositions capable of thermally reversible crosslinking.
