Hydroxybenzophenone-based stabilizers and polymers end-capped with the same

A stabilizer compound (SC) of the general structural formula (I):

• wherein:
• Rj, same or different from Ri, is selected from:
• a first group consisting of a —H, a halogen, a carboxylic ester, an acid halide, an anhydride, an amide, and a thioester,
• a second group consisting of a hydroxyl, an amine, a carboxylic acid, a thiol, and any protected derivatives thereof,
• a moiety of formula (II):
• or
• a moiety of formula (II*):
• and Ri, same or different from each other and from Rj, are selected from the group consisting of —H, —NO2, alkyl groups, alkoxy groups, perfluorinated groups, aryl groups, aryl amine groups, aryl ether groups, aryl sulfone groups, aryl thioether groups, and fused aryl ring systems.
