Abstract Polyethers containing hindered amine side chains as stabilizers The invention relates to polyethers of the formula I Image (I) in which m is 0 or 1; n is an integer in the range from 3 to 100; R1, in the case where m is 0 or 1, is C1-C36alkyl or C7-C36aralkyl, each of which is unsubstituted or substituted by C5-C8cycloalkyl, is interrupted in the aliphatic part by C5-C8cycloalkylene or by oxygen or sulfur or -NR11- or is substituted in the aromatic part by 1 to 3 C1-C4alkyl and/or C1-C4alkoxy radicals; C3-C36alkenyl; C5-C12cycloalkyl which is unsubstituted or substituted by 1 to 4 C1-C4alkyl and/or C1-C4alkoxy radicals; C6-C10aryl which is unsubstituted or substituted by 1 to 4 C1-C4alkyl and/or C1-C4alkoxy radicals; and R1, in the case where m is 0, can alternatively be hydrogen; C1-C36alkoxy or C7-C36aralkoxy, each of which is unsubstituted or substituted by C5-C8cycloalkyl, interrupted in the aliphatic part by C5-C8cycloalkylene or by oxygen or sulfur or -NR11- or is substituted in the aromatic part by 1 to 3 C1-C4alkyl and/or C1-C4alkoxy radicals; C3-C36alkenyloxy; C5-C12cycloalkoxy which is unsubstituted or substituted by 1 to 4 C1-C4alkyl and/or C1-C4alkoxy radicals; or C6-C10aryloxy which is unsubstituted or substituted by 1 to 4 C1-C4alkyl and/or C1-C4alkoxy radicals; R11 is C1-C18alkyl, C5-C8cycloalkyl, phenyl or C7-C9phenylalkyl; and X is an oxygen or sulfur atom.
