Abstract
Poly(alpha-methylstyrene) with narrow molecular weight distribution (MWD) was obtained by cationic polymerization initiated by iodine in CH 2 Cl 2 /liquid SO 2 (80/20 vol.%) or tuluene/liquid SO 2 (45/55 vol.%) mixed solvent at -60°C. The average number molecular weights of the product polymers increased with monomer conversion but the dependence was not linear because of the low initiation efficiency at the beginning of the reaction. On addition of a fresh feed of monomer at the end of polymerization, the added feed was polymerized at the same rate with an increase of molecular weight.
