Abstract
A method for the preparation of a labelled polymer is presented. The method comprises mixing polymer precursors with a marker and polymerizing the polymer precursors to form a labelled polymer or, alternatively, mixing a polymer with a marker to form a labelled polymer. The method is characterized in that the marker comprises or consists of particles, which comprise or consist of a metal and/or a semimetal, the marker having at least three atomic species having a different atomic number. A marker and a labelled polymer are also provided. In addition, uses of the marker according to the invention are proposed. The marker according to the invention does not significantly affect the properties of the polymer and allows coded information in a wide variety of polymers to be read out in a simple and rapid manner and over long polymer lifetimes.
