As can be seen from the data in table 2, the addition of the cross-linking agent containing the weak coupling bond compound to the acrylate adhesive allows the acrylate adhesive to change the structure and properties of the acrylate adhesive after being immersed in the reducing solution, thereby allowing the acrylate adhesive to be easily removed without leaving adhesive on the structural member.
The foregoing examples are illustrative only and serve to explain some features of the method of the invention. The appended claims are intended to claim the broadest possible scope and the embodiments presented herein are merely illustrative of selected implementations based on combinations of all possible embodiments. It is, therefore, not the intention of the applicant that the appended claims be limited by the choice of examples illustrating the features of the invention. Some numerical ranges used in the claims also include sub-ranges within which variations in these ranges should also be construed as being covered by the appended claims where possible.
