Ring-opening metathesis polymerization (ROMP) of a photochromic 1,2-bis-(3- thienyl)-cyclopentene monomer generated a series of novel polymers. All polymers exhibit reversible light-activated interconversion between their colorless-open and their colored-closed forms.
Selon l'invention, la polymérisation par métathèse avec ouverture du cycle d'un monomère de 1,2-<i>bis</i>-(3-thiényl)-cyclopentène photochrome permet d'obtenir une série de nouveaux polymères qui présentent tous une interconversion photoactivée réversible entre leurs formes ouvertes incolores et leur formes fermées colorées.
