✦ Synopsis

The reaction of 3-(trimethoxysilyl)-1-propanethiol with oligobutadiene yielded modified oligomers that can be cross-linked by the sol-gel process. Properties of the materials can be varied in a wide range due to composition, reaction conditions and processing. The influence of the reaction conditions (H + -concentration, molar ratio silane:water, dilution, temperature) on hydrolysis and condensation and on the properties of the final material has been studied. These materials are obtained in the form of transparent films, stable in air up to 270 8C.
