Heterogene polymeranaloge Reaktionen zwischen Polybutadienepoxiden und anorganischen Feststoffoberflächen

Heterogeneous, polymeranalogous reactions between polybutadieneepoxides (PBDE) and inorganic surfaces (SiO2, Al2O3, hydroxyapatite) were investigated. The composition of the resulting composites was determined by gravimetric methods and expressed as “degree of reaction” (RG). Interface reactions could be followed by spectroscopic methods and by differential scanning calorimetry. The results of the reaction mechanisms are discussed. Infrared and 13C solid state NMR studies suggest that the PBDE macromolecules are linked by bonds to the SiO2 surface and by and bonds to the Al2O3 surface.
