Self-light-stabilized photochromic polymer, its preparation and articles containing same |
| abstract |
The objects of the present invention are: a self-light-stabilized photochromic thermoplastic or thermoreticulated polymer carrying non-cyclic tertiary amine-functionalized pendant groups; its preparation method; photochromic articles constituted, wholly or in part of such a polymer. Said polymer is obtained advantageously by radical co-polymerization of a composition containing an effective amount of at least one monomer of formula (1), in which: R1 is hydrogen or a methyl group; n is 2 or 3; R2 and R3 are identical or different and represent independently a methyl or ethyl group; and are advantageously identical; said monomer providing said photostabilizing non-cyclic tertiary amine-functionalized pendant groups. |
