A thermoreversible thiol-Michael bond was incorporated into a series of covalently crosslinked polyester networks using base-catalyzed Michael addition polymerization. Variations in acrylate:acetoacetate ratio (crosslink density), thiol-Michael bond content and cure temperature were employed in order to gauge dynamic and rehealing properties. All of the networks investigated in this study were found to display rehealing behavior after being cut at 100 degrees C within 48 h. Increasing the curing temperature to 120 degrees C led to a decrease in time to reheal (<= 8 h), however the network which employed the highest thiol-Michael bond content, coupled with the lower acrylate:acetoacetate monomer ratio, did not recuperate the original crosslink density upon cooling as evidenced by strain recovery values in excess of 100% and a steady decrease in DSC T-g and TGA weight % as a functional of exposure time.
