Most polymers contain quite complex additive systems which are incorporated during manufacture to impart beneficial properties during manufacturing operations, e.g. protective antioxidants, slip agents etc, and during end-use, e.g. antioxidants, u.v. stabilizers, plasticisers and anti-static agents, flame retardants, antioxidants and thermal stabilizers. The first stage in the examination of a polymer, either from the point of view of identifying the polymer or identifying and determining additives present must be to separate gross polymer from gross additives. It may then be necessary as discussed in Chapter 5.1.16 to separate the gross additive fraction into individual additives by a chromatographic procedure in order to facilitate the identification of individual additives.
