Description:
<jats:title>Abstract</jats:title><jats:p>Heterogeneous, polymeranalogous reactions between polybutadieneepoxides (PBDE) and inorganic surfaces (SiO<jats:sub>2</jats:sub>, Al<jats:sub>2</jats:sub>O<jats:sub>3</jats:sub>, 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 <jats:sup>13</jats:sup>C solid state NMR studies suggest that the PBDE macromolecules are linked by <jats:inline-graphic xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="graphic/nueq001.gif" xlink:title="equation image" /> bonds to the SiO<jats:sub>2</jats:sub> surface and by <jats:inline-graphic xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="graphic/nueq002.gif" xlink:title="equation image" /> and <jats:inline-graphic xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="graphic/nueq003.gif" xlink:title="equation image" /> bonds to the Al<jats:sub>2</jats:sub>O<jats:sub>3</jats:sub> surface.</jats:p>
