    摘要： The present invention discloses novel hydrocarbon core polysulfide silanes and methods of preparing the hydrocarbon core polysulfide silanes. Preferably, the silanes of the present invention contain assemblies of a single unit of a hydrolyzable silane group, tethered to one end of a chain of sulfur atoms, and several of these assemblies are bound to a common central hydrophobic core via the other end of the sulfur atoms chain. The hydrocarbon core polysulfide silanes may be incorporated into filled elastomeric compositions providing improved dispersiblity of the filler materials. Mineral fillers may be pre-treated with the hydrocarbon core polysulfide silanes prior to use in elastomeric compositions.

The process involves the thermal isomerization of 1,5,9-cyclododecatriene at temperature between 400° C. and 600° C. followed by an equilibration of the resultant intermediate in either the gas phase or liquid phase at temperature between 180° C. and 375° C. and at pressures ranging from 0.101 kPa to 1.013 kPa. Also disclosed are 1,2,4-trivinylcyclohexane compositions that are enriched in a particular geometric isomer.
