Abstract

A series of α-end-functionalized polymers of styrene and p-methylatyrene were synthesized by living cationic polymerizations in CH 2 Cl 2 at -15°C initiated with the HCl adducts [2; CH 3 CH(OCH 2 -CH 2 X)Cl; X=chloride, benzoate, acetate, phthalimide, methacrylate] of vinyl ethera carrying pendant substituents X that serve as the terminal functionalities in the products. When coupled with SnCl 4 (activator) in the presence of nBu 4 NCl, these functionalized initiators (2) quantitatively initiated living polymerizations where the carbon-chlorine bond of 2 was activated by SnCl 4
