Abstract

The addition of stabilizers such as hindered phenols, phosphites, hindered amines, and benzotriazoles to polyolefins provide protection from oxidation due to heat, light, or stress. The level of stabilizer in a polymer is related to polymer performance from the time of processing throughout the polymer's lifetime. As a result, measurement and control of the additive concentration that is melt compounded into the polymer is crucial. Making these measurements in the melt offers many advantages over current off line quality control methods such as GC and HPLC. This paper discusses the on-line method for monitoring the levels of hindered phenols and phosphites in polypropylene. This method is based on UV spectroscopy coupled with fiber optics. Data are presented to show the successful measurement of these additives even in the presence of potential interferants.
