1. A process for preparing sulfur-containing branched organosilane polymers comprises:
reacting sulfur with a vinyl silane compound in a solvent and in the presence of a catalytic amount of an accelerator at an elevated temperature of at least 40° C., wherein the concentration of sulfur is from 0.5 to 15 mol·l−1.
