Notes:
Derivatives of 2-hydroxybenzophenone are well-known stabilizers for such polymers as cellulose acetate butyrate and polyesters. Their stabilization effectiveness is commonly associated with their ability to screen a polymer from the harmful ultraviolet radiation found in sunlight. They also satisfy other requirements for effective stabilizers, namely, compatibility with many polymers and an inherent stability to ultraviolet light. Several other functions of 2 hydroxybenzophenones in stabilizing a polymer to ultraviolet light have been postulated, but little experimental data related to them are available. This paper deals with some of the additional functions of 2-hydroxybenzophenones in weathering stabilization as investigated by nuclear magnetic resonance spectroscopy (NMR) and electron paramagnetic resonance spectroscopy (EPR).
