OPTICAL POLYMER MATERIALS WITH HIGH REFRACTIVE INDEX AND LARGE THERMO-OPTIC COEFFICIENT

摘要

PURPOSE: An acryl monomer compound containing sulfide and linear polyurethane and UV-cured polyurethane compound are provided to induce high fraction rate. CONSTITUTION: An acryl monomer compound is denoted by chemical formula 1 or 2. An acryl derivative compound of chemical formula 3 or 4 is formed from the compound of chemical formula 1 or 2. A polyurethane compound is prepared by reacting isocyanate or derivative thereof with one or more compounds selected from chemical formulas 1-4. The isocyanate compound is toluene diisocyanate(TDI), p-phenylene diisocyanate(PPDI), 1,6-hexamethylene diisocyanate(HDI), 1,5-naphthalene diisocyanate(NDI), or isoprene diisocyanate(IPDI).
