Process for the preparation of ethers estu00e9ricamente disabled of the formula I, where R1, R2, R3 and R4 independently of one another, are ohidroxialquilo C1 C1 alkyl - 8 - 5Or R1 and R2 together with the carbon Atom to which they are United soncicloalquilo C5 12, or R3 and R4 with the carbon Atom are United are the same alcual cycloalkyl; C5 - 12; R5, R6,R7, R8 and R9 are, independently of one another, C1 - 8 h, alkyl, aryl alquenilo C2 - C5 - 8, 12, haloalquilo c1-4, an electron donor Group, aryl or C6 12.It is replaced by a residue Selected c1-4 alkyl, c1-4 alkoxy,Halogen; and R7 and r8juntos can also form a Chemical Bond; and R is an organic Group containing 2 - Union with 500 carbon Atoms and Atoms which is directly connected toAnd the nitrogen Atom, to form a cyclic Ring structure of 56 or 7 members; which is characterized in that a compound of the formulaii where all residues - R and R1 R9 are defined according to formula I, is oxidized.The Compound of the formula I can hidrogenarse halogenarse pormu00e9todos and / or Conventional.The compounds of formula I and the corresponding Hydrogenated and / or halogenated compounds are suitable as stabilizers for Organic paramaterial against the degradation of Light,Oxygen and / or heat or yellowish; some are also active as dellama retardant agents.Compounds, compositions, use of these compounds as stabilizers for Organic Materials against degradation due to light, Oxygen, or hot,Process for Stabilizing an organic material against the degradation of Light, oxygen and / or by the application of Heat Stabilizer of a Stabilizer or laincorporacion in said materialAnd use of such compounds as flame-retardant agents to an organic Polymer.
