摘要： An amide particularly suitable as a light stabilizer and also for copolymerizing with other monomers, wherein said amide has the following structure: ##STR1## where R.sub.1 is an aryl radical having the structure: ##STR2## WHERE A AND A' ARE SELECTED FROM HYDROGEN, HYDROXYL AND MEDIUM ALKYL HYDROCARBON RADICALS; B AND B' ARE SELECTED FROM HYDROGEN AND MEDIUM TO LOWER ALKYL HYDROCARBON RADICALS, AND C IS SELECTED FROM MEDIUM TO LOWER ALKYL HYDROCARBON RADICALS, ARYL KETONE RADICALS, 2'-HYDROXY ARYL KETONE RADICALS AND 4'-OCTYL ARYL KETONE RADICALS; R.sub.4 is selected from the aryl radicals of R.sub.1 and from aliphatic hydrocarbon radicals having from 1 to 8 carbon atoms; R.sub.2 is selected from hydrogen, methyl, ethyl, phenyl and --CH.sub.2 X radicals, where X is selected from chlorine, bromine or fluorine radicals; R.sub.3 is selected from medium and lower alkyl, cycloalkyl and aryl radicals; and where R.sub.5 is selected from hydrogen, methyl and chlorine radicals.
