Highly effective UV stabilizing systems can also be achieved by using synergistic mixtures of photoantioxidants/stabilizers with complementary antioxidant mechanisms, e.g. the use of combinations of nickel complexes of dithioic acids, NiDRC, NiDRP, with UV absorbers such as UV531, or hindered piperidine light stabilizers with UV absorbers, e.g. the benzotriazoles. 

A multidimensional system using capillary SEC-GC-MS was used for the rapid identification of various polymer additives, including antioxidants, plasticizers, lubricants, flame retardants, waxes and UV stabilizers (12). This technique could be used for additives having broad functionalities and wide volatility ranges. The determination of the additives in polymers was carried out without performing any extensive manual sample pretreatment. In the first step, microcolumn SEC excludes the polymer matrix from the smaller-molecular-size additives. There is a minimal introduction of the polymer into the capillary GC column. Optimization of the pore sizes of the SEC packings was used to enhance the resolution between the polymer and its additives, and smaller pore sizes could be used to exclude more of the polymer...
