Abstract
Different copolymers of styrene and 4-vinylpyridine were prepared usin g an easy set-up 'living' free-radical polymerization method. After re action with spiro[cyclopropene-1,9'-fluorenes] on to the pyridine subu nits, photochromic coploymers are obtained with controlled weight. Com pared to corresponding free dihydroindolizine, a slight bathochromic s hift is observed.
