ABSTRACT:
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 polymerizable aromatic vinyl compounds wherein, except for the vinylic hydrogen atoms, aromatic C—H bonds are replaced by C—X bonds, where X is a halogen or other selected substituent having a de minimus number, if any, of C—H bonds; for example, without limitation, highly fluorinated fluoroalkanes. In addition, the compounds of the invention have a de minimus number, if any, of N—H and O—H bonds.
