摘要：We report the stereoselective copolymerization of amino-functionalized styrenic monomers, including p-N, N-dimethylaminostyrene (DMAS), p-N, N-diethylaminostyrene (DEAS) and p-N, N-diphenyl-aminostyrene (DPAS) with butadiene (BD) using a half-sandwich scandium catalyst system (C5Me4SiMe3)Sc(CH2C6H4NMe2-o)(2)/[Ph3C][B(C6F5)(4)]. The chain-transfer reaction was efficiently inhibited with the growing steric hindrance of the amino groups. The stereoregular multiblock DEAS-BD and diblock DPAS-BD copolymers were generated with adjustable polymer compositions, controllable molecular weights and narrow molecular weight distributions.
