Abstract
This work had as an objective the development of polymeric coupling agents by introduction of silane groups into liquid polybutadienes of high vinyl content. A fraction of the pendant vinyl groups were converted to organic silane moieties by addition of monomeric silane to the double bond. Platinic chloride was found to catalyze the reaction, and the amount of silanation could be controlled by varying the proportion of reagents. The trichlorosilane pendant groups were further reacted with methyl and ethyl orthoformates yielding triethoxy and trimethoxy derivatives. The silanation could be performed up to the point of complete disappearance of infrared unsaturated bands, thus yielding silane-substituted polymers. Monomeric analogs also have been prepared. The polymers were used to treat glass for coupling with liquid polybutadiene matrix.
