Original Kurzfassung:
Methylated melamines are widely
used as anti-tumor drugs, insect
sterilants, and as monomers for
modified melamine-formaldehydepolymers.
Methylol(methylmelamines) are
metabolites of antitumor agents
such as altretamine
(hexamethylmelamine) and
trimelamol
(trimethylol(trimethylmelamine)), formed by oxidation of a methyl group and subsequent elimination of
formaldehyde. N -vinylmelamine derivatives 2 offer a broad range of industrial applications, not only
homopolymerization but also copolymerization with other monomers currently being under investigation. Our
recent studies have used methylmelamines 1 as building blocks for the synthesis of functional acrylate
monomers for coatings or in the synthesis of polymer additives. In attempt to produce new melamine
polymers we have prepared different functional triazine compounds for further vinylation and then
polymerization with commercially available monomers, such as ethylene, styrene, or methylmethacrylate. The
vinylgroup is usually attached to a free NH-group ? the influence of different substituents on the nitrogen on
the rate of vinylation has been investigated and found to be of great importance. At the moment
copolymerization of the vinyl melamines is being done. Depending on the selected melamine derivative basic
polymerization parameters have been studied and optimized
