Triazolines are formed by the cycloaddition of an azide and a suitable dipolarophile such as maleimide or norbornene under mild conditions and without catalyst. Herein we present the synthesis of main-chain poly(triazoline) linear polymers using bis-maleimide and difunctional azido building blocks. We investigate the poly(triazoline) stimuli responsive behavior given the propensity of triazolines to ring contract to aziridines under photochemical and thermal treatment. Spectroscopic data supporting the formation of aziridine units in the backbone of the polymer after photochemical or thermal treatment will be presented.
