The invention is directed to polymerizable vinyl compounds having halogenated aromatic groups and to a method of synthesizing such compounds. In particular, the invention is directed to vinyl aromatic compounds having the formula
P2C=CP-C6X5-nZn,
in which
(a) P = H, D or mixture thereof;
(b) Z = -Y-C6X5, -Y-W-U-[(o-, m-, p-C6X4-CP=CP2)]m , -Y-V and mixtures thereof;
(c) independently, Y and U = O, S, NH, or is not present;
(d) V and W are respectively a monovalent group and a linking group selected (in each case) from the group consisting of aromatic, polycyclic aromatic (fused-ring), 5- or 6-member heterocyclic aromatic and polycyclic-heterocyclic compounds, and derivatives thereof wherein one or more ring C-H bonds are replaced by C-X bonds, where X = F, Cl, CF3 and Rf, and mixtures thereof, and Rf is a C2-C5 hydrocarbon in which 50% or more of C-H bonds are replaced by C-F bonds;
(e) X = F, Cl, CF3 and Rf, and mixtures thereof, and Rf is a C2-C5 hydrocarbon in which 50% or more of C-H bonds are replaced by C-F bonds; and
(f) m and n are integers in the range of 1-3. The compounds on the invention, when used as polymeric materials in optical communications devices result in devices with low power losses.
