Summary: | PCT No. PCT/EP95/04546 Sec. 371 Date May 22, 1997 Sec. 102(e) Date May 22, 1997 PCT Filed Nov. 18, 1995 PCT Pub. No. WO96/17002 PCT Pub. Date Jun. 6, 1996Compounds of formula (I) (I) in which m+n is a number from 1 to 100 and n varies from zero to 90% of the sum of m+n; R1 and R3, which may be identical or different, are for example C1-C18alkyl or phenyl; R2 is C2-C12alkylene; G is for example a group of formula (IId) (IId) in which R5 and R6 are for example hydrogen; R4 is for example C1-C18alkyl; L1 has for example any one of the meanings given to R1 or is a group (R28)3SiO- where R28 is C1-C18alkyl; and L2 is for example hydrogen, Na, K, C1-C8alkyl or a group (R28)3Si- with R28 as defined above. The compounds of formula (I) are useful as light, heat and oxidation stabilizers for organic materials. |
