ABSTRACT

The efficiency of photochemical transformations of 1′,3′,3′-trimethyl-6′-formyl-8′-allylspiro[2H-1-benzopyran-2,2′-indoline] in PMMA modified with small amounts of poly(ethyl acrylates) of different structures is studied. It is shown that, in the presence of these additives, the quantum yield of the coloring reaction of the photochromic compound under UV irradiation and the rates of photochemical reactions (forward and back) increase. The maximum efficiency of photochemical parameters is observed for PMMA containing small amounts of linear poly(ethyl acrylate) occurring as a microphase in a glassy matrix. More... »
