Lightly cross‐linked natural rubber was found to have a tunable trigger‐temperature through programming procedure. Solvent vapor has a further impact on the trigger‐behavior of programmed SMNR. For exploring this we used the 1 st derivative of the temperature dependent thickness increase to get insights in the trigger‐behavior. Additionally subsequently applied solvent vapor treatment allows reversibly changing T Trig as well as the maximum trigger‐rate ν max and thus the whole trigger‐process. The variation of solvent vapors or subsequently applied solvent combinations results in a novel way to alter the trigger‐behavior after programming.
