The polymerization process of conjugated diolefins (dienes) using rare earth catalysts in the presence of vinyl aromatic solvents

摘要

The invention relates to a method for polymerizing conjugated diolefins in the presence of catalysts of rare earths and in the presence of aromatic vinyl compounds, and to the use of these diolefins for producing rubber-modified molding materials, especially of the ABS type and impact-resistant polystyrene (HIPS).
