Understanding the relationship between structure and mechanochemical reactivity is crucial for designing new stimuli-responsive polymers. In this study, we validate an initial rates method that accurately determines rate constants for ultrasound-induced mechanochemical transformations. The experimental results support the effectiveness of this method in deconvoluting the kinetics of specific mechanophore activation from nonspecific chain scission.
Understanding structure-mechanochemical reactivity relation-ships is important for informing the rational design of new stimuli-responsive polymers. To this end, establishing accurate reaction kinetics for mechanophore activation is a key objective. Here, we validate an initial rates method that enables the accurate and rapid determination of rate constants for ultrasound-induced mechanochemical transformations. Experimental reaction profiles are well-aligned with theoretical models, which support that the initial rates method effectively deconvolutes the kinetics of specific mechanophore activation from the competitive process of nonspecific chain scission.
