Method for polymerizing conjugated diolefins (dienes) with catalysts of rare earths in the presence of vinyl aromatic solvents

摘要

The present invention provides a method for polymerizing conjugated diolefins in the presence of a catalyst of the rare earth metals and in the presence of an aromatic vinyl compound. The diolefins produced thereby may find use in producing rubber-modified molding materials, such as ABS and HIPS.
