Abstract
A rubbery polymer with a relatively high 1,2-structure content is formed by polymsg 2,3-dimethyl-1,3-butadiene in the presence of an org. Li catalyst in a solvent chosen from benzene, toluene, ethylbenzene, xylene or naphthalene the solvent comprising >=20% of the mixt. The prod is suitable for producing pneumatic tyres.
