1,3-BIS(2-HYDROXYHEXAFLUOROISOPROPYL)-4-FLUOROBENZENE DIACRYLATE OR DIMETHACRYLATE, POLYMER MATERIAL AND PHOTO-SETTING DENTAL RESIN COMPOSITION CONTAINING THE SAME AS COMPONENT

摘要

NEW MATERIAL:1,3-Bis(2-hydroxyhexafluoroisopropyl)-4-fluorobenzene diacrylate or dimethacrylate expressed by formula I (R is H or methyl). USE:Useful as various polymer cross linking agents or optical, dental and functional polymer materials. The above-mentioned compound is good in compatibility with other monomers, excellent in cold curability, especially photo-setting properties with a low refractive index and applicable to the field, such as optical materials, requiring conformability with refractive index of silica glass. PREPARATION:The corresponding diol and acryloyl or methacryloyl chloride are subjected to dehydrochlorinating reaction to afford the compound expressed by the formula I.
