Title:
NOVEL PHOTOCHROMIC POLYMERS AND METHODS OF SYNTHESIZING SAME
Document Type and Number:
WIPO Patent Application WO2002006361
Kind Code:
A3
Abstract:
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.
