In the present contribution we present the results of a study aimed at investigating the influence of different modifying agents on the interactions between silica and elastomers and then on the disperdability of the filler in the elastomer matrix. A precipitated silica has been treated with triethoxysilane (TES) and different amounts of bis-triethoxysilipropyltetrasulfane (TESPT); its surface characteristics where examined by FI-IR and inverse gas chromatography (IGC). The previsions deduced from these studies are compared with some preliminary results obtained from tensile measurements and morphological observations carried out on SBR based compounds loaded with different amounts of modified silica.

Abstract
In the present contribution we present the results of a study aimed at investigating the influence of different modifying agents on the interactions between silica and elastomers and then on the disperdability of the filler in the elastomer matrix. A precipitated silica has been treated with triethoxysilane (TES) and different amounts of bis-triethoxysilipropyltetrasulfane (TESPT); its surface characteristics where examined by FI-IR and inverse gas chromatography (IGC). The previsions deduced from these studies are compared with some preliminary results obtained from tensile measurements and morphological observations carried out on SBR based compounds loaded with different amounts of modified silica.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
