    Why does styrene undergo anionic polymerization easily?

    Anionic polymerization takes place with monomers possessing electron-withdrawing groups such as nitrile, carboxyl, phenyl, and vinyl. In styrene, an electron withdrawing phenyl group is attached to the doubly bonded carbon atom (CH2 = CH–C6H5), hence it is able to stabilise the anionic propagating species.
