BLOCK OLIGOMERS CONTAINING 1-HYDROCARBYLOXY-2,2,6,6-TETRAMETHYL-4-PIPERIDYL GROUPS AS STABILIZERS FOR ORGANIC MATERIALS |
摘要 |
Compounds of formula (I), wherein n is a number from 2 to 14; R1 is for example C1-C18alkyl or C5-C12cycloalkyl; R2 is for example C2-C12alkylene; A is for example acetyl, (C1-C4alkoxy)carbonyl, (C1-C4alkyl)aminocarbonyl or C1-C4alkyl; B is -OR3, -N(R4)(R5) or a group of formula (II); R3, R4 and R5, which are identical or different, are for example hydrogen or C1-C18alkyl, or -N(R4)(R5) is additionally a group of formula (III) with Y being -O-, -CH2-, -CH2CH2- or >N-CH3; X is -O- or >N-R6; R6 is for example hydrogen or C1-C18alkyl; and R is preferably a group of formula (IV); with the proviso that in the individual recurrent units of formula (I), each of the radicals B, R, R1 and R2 has the same or a different meaning. The indicated compounds are useful as light stabilizers, heat stabilizers and oxidation stabilizers for organic materials, in particular synthetic polymers.
