For the manufacture of our particles we routinely use monomers of styrene, alkyl methacrylates, melamine-formaldehyde, glycidyl methacrylate, vinyl acetate and vinylpyrrolidone, which are polymerised by different methods (Fig.). For special requirements, it is sometimes possible to produce copolymer particles with defined graded properties by mixing the basic materials with other functional monomers. Furthermore, we have defined degrees of crosslinking, which are realised through methacrylate divinylbenzene, ethylene glycol and allyl (Fig.). As mentioned, variations in the basic properties such as density, refractive index, hydrophobic/hydrophilic properties, stability in solvents and/or at higher temperatures and functionalisation can be adjusted as desired.
