| Abstract: | Copolymerization of styrene and a-methylstyrene initiated by n-butyllithium in cyclohe-xane with tetrahydrofuran as a polar solvent has been performed. Through the investigation of copolymer composition and active species, the copolymer composition equation which applies in this system was derived based on the mechanism. The apparent reactivity ratios of two monomers were obtained. The effect of tetrahydrofuran concentration on the apparent reactivity ratios of monomers was discussed. |
