ROMP como um método versátil para a obten？？o de materiais poliméricos diferenciados

ring opening metathesis polymerization (romp) of cyclic olefins is a powerful transition metal-catalyzed reaction for syntheses of polymers and copolymers. the key feature of this reaction is the [2+2]-cycloaddition mechanism, with retention of the olefinic unsaturation in the polymer chain and occurrence of living polymerization. with the development of metal-carbene type catalysts for this process, many addressed polymeric materials have been successfully prepared to be employed in several fields of the science and technology. this review summarizes recent examples of syntheses of polymers with amphiphilic features such as block, graft, brush or star copolymers; as well syntheses of biomaterials, dendronized architectures, photoactive polymers, cross-linked or self-healing materials, and polymers from renewed supplies.
