Molecular Design of Stimuli Responsive PolymersnStephen Craig, Duke UniversitynnThe mechanical properties of polymers are the result of entanglements¬¬––physical interactions between individual polymer molecules that allow mechanical forces to be transmitted from one molecule to the next. Polymeric materials, therefore, become stimulus-responsive when the entanglements that define them are stimulus-responsive. Typically, however, those entanglements are set by the effectively permanent che
