ABSTRACT:
Polymers whose repeating units are of structure ##SPC1##
Are prepared by polymerization of novel biphenylyloxybenzoyl moiety-containing monomers reactive in HF and BF.sub.3 to form carboxonium ion-containing intermediates (e.g., biphenylyloxybenzoyl halide monomers), preferably in the presence of aromaic capping agents sufficient in amount to yield polymer of mean inherent viscosity from about 0.5 to 1.7. Such polymer may be employed, e.g., for insulative coating of conductive articles such as wire and cable.
