Abstract:

 

Monodisperse poly(N,N-dimethyl-4-vinylphenethylamine)-block-polystyrene was synthesized via anionic living polymerization carried out at -78 °C   under a pressure of 10-6 torr using cumyl potassium as  the initiator.  Subsequent photoinduced radical polymerization of  styrene through side chain-functional N,N-dimethyl amino groups  yielded a crosslinked polymer and a brush type block-graft copolymer  to a lesser extent.  Upon irradiation at a wavelength of 350 nm,  macroradicals were generated via hydrogen abstraction from amino  side-chain groups by the excited benzophenone.  The block-graft  copolymer was characterized by 1H-NMR, IR, and GPC analysis.
