摘要：
Compounds having the formula
where R¹, R², R³, R⁴, and R⁵ are independently selected from hydrocarbons, n is an integer of 1 to 15, and Y is H, OH, O, or OR where R is a hydrocarbon are useful as stabilizers for polymers against the detrimental effects produced by exposure to actinic radiation, such as visible or ultraviolet light rays.
