Abstract
A composition for sealing defects in structural materials such as roads or paved surfaces, the composition preferably comprising one or more shape memory polymer (SMP) components capable of responding to increased temperature by decreasing in volume. Smart SMP-based sealants of the invention serve to avoid adhesion failure between a sealant and the repaired structure when the repaired structure is subjected to varied temperatures that cause thermal expansion and contraction.
