Abstract
La presente invención se refiere a poliorganosiloxanos mixtos que tienen por moléculas (i) por lo menos una unidad siloxilo funcional (I), en donde R1representa un radical alquilo C1 a C4 o fenilo, contiene una función amina cíclica secundaria o terciaria, ligada al silicio por un enlace -Si-A-C siendoA un átomo de oxígeno o el radical -CH2-CHR2-COO- (siendo R2 un átomo de hidrógeno o un radical alquilo C1 a C3), y a = 0, 1 ó 2; (2i) por lo menos otraunidad funcional (II), en donde W representa una función compatibilizante que consiste particularmente en un radical alquilo que tiene más de 10 átomos decarbono y b = 0, 1 ó 2; y eventualmente (3i) por lo menos otra unidad (III), en donde d = 0, 1, 2 ó 3, y e = 0 ó 1, y la suma d + e es como máximo igual a 3.Dichos poliorganosiloxanos se emplean en los polímeros para mejorar particularmente su fotoestabilización.
