1. An adhesive comprising:
a polymeric adhesive matrix; and
a carboxylic acid or a salt thereof dispersed within the polymeric adhesive;
wherein the carboxylic acid has the structure

OG Complex Work Unit Chemistry
where n is 2, 3 or 4;
the carboxylic acid or a salt thereof is present in an amount greater than 2.5% to about 15% by weight based upon a total weight of the adhesive; and
wherein after the adhesive has been cured and then exposed to microwave radiation having a frequency of about 2.4 GHz and a power level of at least 900 W for a period of time of at least 60 seconds, the adhesive has a bond strength that is less than 30% of a reference bond strength for the otherwise same adhesive except without the carboxylic acid or salt thereof, when exposed to about the same frequency of microwave radiation for about the same period of time, and when used to bond the same materials and measured under the same conditions.
