| 摘要 |
This invention relates to copolymerizable ultraviolet light absorber compounds having the formula: <CHEM> where (Ar)1 and (Ar)2 are aromatic carbocyclic nuclei of the benzene and naphthalene series and are independently selected from phenyl or phenyl substituted with alkyl, halo, alkoxy, carboxy, carbalkoxy, cyano, acetyl, benzoyl, phenyl, alkyl phenyl, phenoxy phenyl, alkyl substituted phenoxy, or alkoxy phenyl substituted phenyl and naphthyl; X is alkylene, C2-C17, unsubstituted or substituted with halo, cyano, alkyl, alkoxy, alkoxyalkyl or alkoxyalkyleneoxy, C1-C6: and, Y is a copolymerizable radical selected from acryloyl, alkylacryloyl, acryloxyalkyl, acryloxyhydroxyalkyl and alkylacryloxyhydroxyalkyl, C3-C12; or -RCR=CHR sec , where R is alkylene, oxyalkylene, alkyleneoxyalkylene, phenylene, C1-C10, unsubstituted or substituted with hydroxy and R min and R sec are independently hydrogen or alkyl, C1-C10. In other aspects of the invention, it relates to methods of making these compounds and to intermediates formed during their synthesis. |
