ABSTRACT:
This invention relates to (acetoxyalkyl) 2-cyano-3,3-diphenylacrylate intermediates having the formula: ##STR1## where (Ar).sub.1 and (Ar).sub.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; and,
X is alkylene, C.sub.2 -C.sub.17, unsubstituted or substituted with halo, cyano, alkyl, C.sub.1 C.sub.6, alkoxy, C.sub.1 -C.sub.6, alkoxyalkyl, C.sub.1 -C.sub.6 or alkoxyalkyleneoxy, C.sub.1 -C.sub.6.
These intermediates are used in making (2-cyano-3,3-diphenylacryloxy) alkylene acrylic esters and (2-cyano-3,3-diphenyl) alkylene ethylenic ethers, which compounds are copolymerizable, ultraviolet light absorbers.
The intermediate compounds are made by:
