Synthesis, Characterization and Performance Evaluation of Polymeric Hindered Amine Light Stabilizers in Styrenic Polymers

摘要

Most commercially available polymers are stabilized against thermal and photo-oxidative degradation with conventional stabilizers. This is achieved by blending the polymer with appropriate stabilizers, which ensure that the desirable polymer properties are maintained throughout its service life. For proper functioning of any additive, its chemical structure is also important. For longer stability of the polymer, the stabilizer must remain in its matrix in the active form.
