Thermally-responsive materials have been prepared in a multitude of ways for a wide variety of applications. One aspect not previously exploited is the ability to change the molecular weight for dynamic processing. Diels-Alder (DA) chemistry was incorporated within the main chain of the polymer backbone by using a DA-initiator and atom transfer radical polymerization. Next, polymer were utilized as macromonomers and coupled into high molecular species via atom transfer radical coupling. Upon the application of a thermal stimulus, the retro-DA was induced and molecular weight of the polymer was altered. <br/>
