Polymerizable cyclic compounds

Claim 1

A LIQUID SOLUTION MAINTAINED AT A TEMPERATURE BELOW ABOUT MINUS 45*C. AND CONTAINING A STABLE CONCENTRATED POLYMERIZABLE CYCLIC COMPOUND CHARACTERIZED AT LEAST AT ONE ENERGY LEVEL BY HAVING A QUINOLD STRUCTURE AND CHARACTERIZED BY BEING READILY REACTABLE WITH IODINE TO PRODUCE A DIIODO COMPOUND OF A GROUP CONSISTING OF 1,4DIIODOMETHYL BENZENE, 1,4 DIIODOMETHYL NAPHTHALENE, CORRESPONDING HETEROCYCLIC DIIDOMETHYL COMPOUNDS HAVING 1 TO 2 SIX-MEMBERED RINGS AND CONTAINING AT LEAST ONE HETERO NITROGEN ATOM VICINAL ONLY TO CARBON ATOMS, AND THE NUCLEAR SUBSTITUTION PROUDCTS OF THE FOREGOING MEMBERS WITH NORMALLY GASEOUS HALOGEN ATOMS AND WITH METHYL GROUPS AND CONTAINING A LIQUID HAVING A FREEZING POINT BELOW ABOUT -45*C. AND SELECTED FROM THE GROUP CONSISTING OF PARAFFINIC AND CYCLO-PARAFFINIC HYDROCARBONS, AROMATIC HYDROCARBONS, HALOGENATED HYDROCARBONS, CARBONYL COMPOUNDS, ETHERE, ALCOHOLS, CARBON DISULFIDE AND MIXTURES THEREOF.

Claim 2

A METHOD OF PREPARING IN STABLE FORM AND IN A CONDENSED PHASE, A CYCLIC COMPOUND, CAPABLE OF POLYMERIZATION, WHICH COMPRISES PYROLYZING AN AROMATIC COMPOUND OF THE GROUP CONSISTING OF P-XYLENE, 1,4 DIMETHYL NAPHTHALENE, CORRESPONDING HETEROCYCLIC DIMETHYL COMPOUNDS HAVING FROM ONE TO TWO SIX-MEMBERED RINGS AND CONTAINING AT LEAST ONE HETERO NITROGEN ATOM VICINAL ONLY TO CARBON ATOMS, AND THE NUCLEAR SUBSTITUTION PRODUCTS OF THE FOREGOING MEMBERS WITH NORMALLY GASEOUS HALOGEN ATOMS AND WITH ADDITIONAL METHYL GROUPS GASEOUS HALOGEN BETWEEN ABOUT 700*C. AND 1300*C. AND AT A TOTAL PRESSURE NOT HIGHER THAN ABOUT 400 MN. HG FOR A PERIOD OF NOT MORE THAN ONE SECOND, QUENCHING THE PYROLYZED VAPORS TO A TEMPERATURE BELOW ABOUT MINUS 45*C. IN A COLD, SUBSTANTIALLY NON-REACTIVE LIQUID HAVING A PARTIAL PRESSURE AT THE QUENCHED TEMPERATURE BELOW ABOUT 10 MM. HG.
