Hydrogenated polymerized dac-b

Claim 1

AN ORGANIC COMPOSITION PREPARED BY HYDROGENATING, WITHOUT PRIOR SEPARATION INTO SOLID AND LIQUID PORTIONS AND AT AN ELEVATED TEMPERATURE AND PRESSURE N THE PRESENCE OF A METALLIC HYDROGENATION CATALYST, A CRUDE POLYMER SELECTED FROM THE GROUP CONSISTING OF: (A) THE CRUDE HOMOPOLYMER PREPARED BY POLYMERIZING DAC-B IN THE PRESENCE OF AN APROTONIC LEWIS ACIS POLYMERIZATION CATALYST AND (B) THE CRUDE COPOLYMER PREPARED BY COPOLYMERIZING DAC-B AND AN ETHYLENICALLY UNSATURATED DIACYL MONOMER IN THE PRESENCE OF AN APROTONIC LEWIS ACIE POLYMERIZATION CATALYST, WHEREIN SAID DAC-B IS THE LIQUID RESIDUAL FRACTION OF THE DEBUTANIZED RESIDUE FROM THE PYROLYSIS AT A TEMPERATURE OF ABOUT 700 TO ABOUT 800*C. AND A PRSSURE OF ABOUT 10 TO ABOUT 75 POUNDS PER SQUARE INCH GAUGE FOR A PERIOD OF ABOUT ONE SECOND OF A NATURAL GAS STREAM PREDOMINANTLY COMPRISING PROPANE, SAID LIQUID RESIDUAL FRACTION HAVING AN INITIAL BOILING POINT GREATER THAN ABOUT 60*C., AN IODINE NUMBER OF ABOUT 195 TO ABOUT 275, AND CONTAINING ABOUT 87 TO ABOUT 91 PERCENT CARBON AND ABOUT 9 TO ABOUT 13 PERCENT HYDROGEN, AND CAPABLE OF BEING SEPARATED INTO THREE PORTIONS BY DISTILLING WITHOUT HEATING AT 0.1 MM. PRESSURE.
