Abstract: High Resolution Image Download MS PowerPoint Slide Block-like copolymers can be readily synthesized in one step using monomers with widely separated reactivity ratios. Here, we show that trans, trans, trans -1,5,9-cyclododecatriene ( CDT ), produced from polybutadiene via cyclodepolymerization (CDP), undergoes gradient copolymerization via ring-opening metathesis polymerization (ROMP) with a selected norbornene monomer to produce a block-like copolymer that exhibits bulk nanophase separation and excellent thermomechanical performance. These data highlight a new ROMP copolymerization system with a sharp compositional drift and introduce a simple pathway to convert waste plastic into a valuable building block for high-value thermoplastic materials.
