Title:
A THERMOSENSITIVE LIGHT-ADJUSTING MATERIAL AND PROCESS THEREOF, AND AN OPTICAL DEVICE COMPRISING THEREOF
Document Type and Number:
WIPO Patent Application WO/2009/033410
Kind Code:
A1
Abstract:
A thermosensitive light-adjusting material is formed by reacting 18-84% polymer polyols and/or terminal hydroxyl-containing polymers which are formed by reacting polymer polyols and diisocyanate, with 15-80% terminal hydroxy-containing ethylenically unsaturated monomers through light or heat polymerization reaction. A process for preparing the thermosensitive light-adjusting material and an optical device comprising thereof. The light-adjusting ability is high, the light-adjusting range is broad, and mechanical capability is good. The preparation method is simple, short-circle, and high effective, so it can be applied in industry, furthermore, because of no organic solvents, the method's advantages are low cost and without pollution.
