Abstract

PROCEDIMIENTO PARA LA ESTABILIZACION DE POLIMEROS CONTRA LA DEGRADACION POR LA LUZ. CONSISTE EN SOLUBILIZAR EN EL POLIMERO NORMALMENTE SOMETIDO A DEGRADACION POR LA LUZ ULTRAVIOLETA, DE 0,01 A 5 POR CIEN DE UN POLIMERO DE FORMULA (I), EN LA QUE R1 ES ALQUILENO C2-8 O CICLOALQUILENO C5-6; R2 Y R3 SON ALQUILO C1-8 O EN EL CARBONO AL QUE ESTAN UNIDOS FORMAN UN CICLOALQUILO C5-6; R5 ES ALQUILO C1-8 O CICLOALQUILO C5-6; R4 PUEDE SER VARIOS RADICALES; Y X VALE DE 4 A 10. LA SOLUBILIZACION SE LLEVA A CABO POR CALENTAMIENTO DE LA MEZCLA A UNA TEMPERATURA ENTRE 175GC Y 205GC. TIENE APLICACION PARA LA ESTABILIZACION DE PELICULAS DE POLIOLEFINAS Y DE POLIURETANOS AROMATICOS. *FORMULA*.
