Green recycling of unsatured elastomers

Smart polyurethanes were developed from various well defined heterofunctional oligomers obtained through a highly controlled oxidative or methatetic cleavage of unsaturated high molecular weight rubbers. These two methodologies  applicable from either natural source or waste rubber materials allow the access to new materials (antibacterial coatings, flame retardant foams, ionogels,etc…)
