Abstract
Polyalkoxy monovinyl substituted aromatic compounds, such as 3,4-dimethoxystyrene, function as both comonomer and randomizing agent in organolithium initiated copolymerization of a conjugated diene with a monovinyl aromatic compound, such as of butadiene with styrene. The resultant polymeric product exhibits lower levels of block styrene than does a corresponding copolymer made in the absence of the dimethoxystyrene.
