ABSTRACT
A new dimethacrylate monomer 9,9'-bis[4-(2'-hydroxy-3'-methacryloyloxy-propoxy)phenyl] fluorene (3) with a molecular weight of 634 was synthesized in 51.4%yield by addition of a glycidyl ether group to 9,9'-bis(4-hydroxyphenyl) fluorene (1) bythe reaction of compound 1 with epichlorohydrin, and then introducing the methacrylatemoiety by the reaction of the epoxy group with methacrylic acid. The structure ofmonomer 3 was confirmed by FT-IR, 1H-NMR, mass spectra and elemental analysis.
