| titleOfInvention | Sterically hindered amines and use thereof as polymer stabilizers |
| abstract | The present invention relates to polypiperidine compounds capable of conferring to polymeric materials, particularly polyolefins, a high stability against photodegradation and oxidative action of air, which belong to the HALS category and have the following general formula (I) n n n n n n n n n n in which x can be zero or 1;n ny is between 1 and 10;n nm and n, which may be different or equal to each other, range from 2 to 8;n nA represents a NPiR 1 group or a NR 2 R 3 group;n nand Pi represents the group of formula (II)n n n n n n n n n n n wherein R 1 is selected from the group consisting of H, C 1 -C 4 straight-chain and branched-chain alkyl groups;n 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 heteratoms such as O,n R 4 is selected from the group consisting of H, C 1 -C 4 straight-chain and branched-chain alkyl group, and OR 5 group, wherein R 5 is selected from the group consisting of H, C 1 -C 8 straight-chain or branched-chain alkyl groups.n nThe invention also relates to processes for the preparation of the compounds according to the invention. |
