Abstract
La presente invencion se refiere a los N-oxidos de 4-acilaminopiperidina la A+B (Ia) en donde A1 es hidrogeno o un radical orgánico y B1 es un radical IIa. (Ver Formula) en donde R1-R4 son cada uno alquilo de C1-C4, y, R1 y R2, por una parte, y R3 y R4, por otra parte, pueden además estar unidos para formar un anillo de 5 a 6 miembros, R5 es H o alquilo de C1-C4 y R6 es H o alquilo de C1-C18 se utilizan para estabilizar materiales orgánicos contra el efecto danino de los radicales libres, particularmente durante la destilacion de monomeros que sufre de polimerizacion por radicales libres, especialmente el estireno.
