Provided are: an adhesive that offers high adhesiveness to bond and secure an adherend even in a high-temperature environment, as long as securing is necessary. The adherend can be removed without failure and without adhesive residue once securing becomes unnecessary; and a method for processing an adherend using the adhesive. The adhesive according to the present invention contains a multivalent vinyl ether compound (A) and at least one of a compound (B) and a compound (C). The compound (B) is represented by Formula (b). The compound (C) includes two or more constitutional units each represented by Formula (c). Formulae (b) and (c) are expressed as follows: ##STR00001##

A method of using a self-stick insulation. The method includes providing a piece of insulation product with an adhesive coating. The adhesive coating includes polystyrene-maleic anhydride (SMA) and/or polyacrylic acid (PAA); an alcohol amine; and at least one of a polyvinyl alcohol and a starch. The adhesive coating is then activated with liquid water. Once the adhesive coating is active, the insulation product is attached to a surface with the adhesive coating.

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.
