## Abstract The kinetics of polymerization of α‐methylstyrene by __n__‐BuLi (labeled with C^14^ and unlabeled) has been studied in tetrahydrofuran at −78°C. The catalyst __n__‐BuLi was used as a complex of __n__‐BuLi in THF and a hexane solution of __n__‐BuLi. Contrary to expectations, the relative

We have measured the shear viscosity of solutions of living poly(a-methylstyrene) in tetrahydrofuran, initiated by sodium naphthalide, as a function of temperature, mole fraction of initial monomer in solvent, and concentration of the initiator species. For these "living" polymers, the average molec
The concentration of e-methylstyrene in equilibrium with poiy-ct-methylstyryl sodium in tetrahydrofuran as solvent has been measured as a function of polymer concentration (0-.4 base-
The effect of common anion producing salt, tetrabutylammonium chloride (n-Bu 4 NCl), on the livingness and kinetics of styrene (St), p-chlorostyrene ( pClSt), and p-methylstyrene (pMeSt) polymerization initiated by the 2-chloro-2,4,4-trimethylpentane (TMPCl)/TiCl 4 system has been investigated. Unco
