     a novel photoactive gemini surfactant was easily synthesised in high yields. the multi-functional molecule can be used as a gemini surfactant, a benzophenone type photoinitiator, and as an atrp initiator. poly(methyl methacrylate) (pmma) and poly(methyl methacrylate)-block-poly(allyl methacrylate) (pmma-b-pama) were prepared using the photoactive gemini surfactant as an atrp initiator under soap-free miniemulsion polymerisation conditions. kinetic results of the miniemulsion polymerisation of methyl methacrylate (mma) indicate that the reaction has controlled/living characteristics. uv curing was performed by irradiation of the linear pmma-b-pama polymer, in which pmma-b-pama containing a benzophenone moiety functioned as a macromolecular photoinitiator.
