Retardation of the merocyanine-spiropyran conversion in macromolecules

  • 76 Accesses


The flash photolysis of photochromic poly(spiropyranmethacrylate) in solutions was studied. The rates of the thermal decoloration reaction in the polymer solutions are lower than in solutions of the monomer, that was attributed to the steric hindrance of the reaction in macromolecules.
