abstract |
The present invention relates to the use of N,N',N"-substituted hexahydro-1,3,5-triazines in the anionic polymerization of conjugated diene monomers and vinylarene monomers. The use of this polar additive results in Copolymers with both high vinyl aromatic content and low vinyl content at the same time, the degree of blocking of vinyl aromatic units can be adjusted. |
