Notes:
To prepare the copolymer, which is water and oil repellent and contains the hydroxyl group, 2-methoxy-4-vinylphenol (VG: M1) is copolymerized with the fluorinated acrylic monomer (M2). The copolymerizability of VG (vinyl guaiacol) with pentadecafluoroctylacrylate (PDFOA) is best (r1 = 0.217, r2 = 0.0751). The critical surface tension γC of the copolymer of F1 = 0.451 (F1 is the ratio of M1 units in the copolymer) is estimated to be 13.5 dyne/cm which is close to that of the homopolymer (F1 = 0). The γc of the other copolymers are so small that they are 18.5 dyne/cm for copoly(VG-trifluoroethylmethacrylate) of F1 = 0.491 and 17.8 dyne/cm for copoly(VG-fluoro-pentylmethacrylate) of F1 = 0.392. Thus, these copolymers are water and oil repellent. Further, because of the hydroxyl, they provide hydrogen bonding to hydroxyapatite of teeth.
