摘要：
Random copolymers of a conjugated diene and at least 50% by weight of a vinyl aromatic compound are prepared by slowly reacting the monomers in a non-polar solvent in the presence of a chelating modifier such as ethylene glycol diethyl ether which results in at least 50% 1,2-polymerization of the conjugated diene.
