Polytechnic University, Brooklyn, NY 11201 Most polymers must be stabilized against the impact of the environment. Antioxidants and ultraviolet (UV)stabilizers are of vital importance to protect polymeric materials from deterioration. To be effective UV absorbers, these compounds must also have the capability to dissipate the energy without causing damage. Long range and efficient protection of organic polymeric materials from the environment requires carefully designed and stabilizing systems including polymerbound UV stabilizers.
