Abstract
Se proveen poliuretanos, poliureas y polímeros de poliuretano-poliurea, estabilizados, que tienen fotoestabilizadores él amina impedida (FEAI) unidos a ellos por medio de una funcionalidad hidrazida unida a los FEAI. El efecto sinergístico de un segundo grupo funcional amida en la hidrazada de FEAI, provee eficiencia mejorada en la fotoestabilización, en comparación con las hidrazidas de FEAI de la técnica anterior.
