    Abstract: There are provided polymer bound hindered amine light stabilizers with recurring units selected from
    or both in which the units occur, e.g., in the polymer backbone and wherein R¹ and R² are, e.g., hydrogen or alkyl of 1 to 6 carbons, x is an integer of 0 or 1, and G has the structure
    wherein X is, e.g., -Z-C(=O)-R⁹-C(=O)-N(R⁸)- where Z is, e.g., -N(R¹⁰)-, R⁹ is, e.g., a direct bond and R⁴, R⁵, R⁶, R⁸ and R¹⁰ are, e.g., hydrogen. They are prepared by reacting hindered amine light stabilizers containing reactive hydrazide functionalities with anhydride containing polymers or copolymers. The reactions may be carried out in an inert solvent or in a melt blending step. The polymer bound hindered amine light stabilizers are useful alone or may also be used to stabilize other polymers, copolymers or polymer blends against the deleterious effects of heat and/or light.
