Patent ID: 8404765

Claim:
Stabilizing compounds with general formula (I) in which x=1; y is between 1 and 10; m and n, which may be different or equal to each other, range from 2 to 8; A represents a NPiR 1 group or a NR 2 R 3 group; and Pi represents the group of formula (II) wherein R 1 is selected from the group consisting of H, C 1 -C 4 straight-chain and branched-chain alkyl groups; R 2 and R 3 can be the same or different and are selected in the group consisting of H, C 1 -C 8 straight-chain and branched-chain alkyl groups, cyclic alkyl groups having from 5 to 12 carbon atoms, or form together with the nitrogen atom a heterocyclic ring having from 5 to 7 members, comprising other heteroatoms; R 4 is selected from the group consisting of H, C 1 -C 4 straight-chain and branched-chain alkyl groups, and OR 5 , wherein R 5 is selected from the group consisting of H, C 1 -C 8 straight-chain or branched-chain alkyl groups wherein the end groups of the compounds of formula (I) are selected from the group consisting of H, OH, OR wherein R is an alkyl group, and amine groups of formula (V)
