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 amide-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 the formula: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. |
