Abstract: Vinyl or vinylidene monomers are polymerized in solution in a non-polymerizable hydrocarbon solvent in the presence of a catalytic amount of dispersed sodium and up to 1.0% by weight, based on monomer present, of a dialkyl ether of a dihydric alcohol, e.g. the dimethyl ethers of ethylene, diethylene, triethylene and tetraethylene glycols. Monomers specified are styrene, alpha-methyl styrene and vinyl naphthalenes and mixtures thereof. Hydrocarbon solvents specified are pentane, hexane, cyclopentane, cyclohexane, benzene, toluene and xylene.
