    Abstract: 1. AN IMPROVED ALKANE ISOMERIZATION PROCESS WHICH COMPRISES ISOMEERIZING NORMAL PARAFFINS HAVING FROM 4 TO 8, INCLUSIVE CARBON ATOMS TO SKELETAL ISOMERS CONTAINING THE SAME NUMBER OF CARBON ATOMS BY CONTACTING THE PARAFFINS UNDER ISOMERIZATION CONDITIONS WITH A LIQUID PHASE CATALYST SELECTED FROM THE GROUP CONSISTING OF ARSENIC PENTAFLUORIDE, ANTIMONY PENTAFLUORIDE, AND MIXTURES THEREOF WITH EITHER TRIFLUOROMETHANESULFONIC ACID OR HDROGEN IN THE PRESENCE OF SUFFICIENT HYDROGEN TO PROVIDE A HYDROGEN PARTIAL PRESSURE OF 900-4000 P.S.I.G. DURING SAID ISOMERIZATION TO SUPPRESS CRACKING OF PARAFFINIC REACTANTS TO LESS DESIRABLE CRACKED PRODUCTS AND INCREASE SELECTIVELY TO DRSIRED ISOMERIC PRODUCTS.

    Abstract: 1. A solid propellant composition comprising an oxidant of inorganic oxidizing salt and a binder of solid polymer formed by reacting in combination a compound containing 3 aziridinyl groups per molecule and a compound containing only 2 aziridinyl groups per molecule with an uncured polymer of a monomer selected from the group consisting of conjugated dienes having 4 to 12 carbon atoms per molecule, aryl-substituted olefins, pyridine and quinoline derivatives containing at least one member of the group consisting of vinyl and alphamethylvinyl, acrylic acid esters, alkacrylic acid esters, vinylfuran and vinylcarbazole, said uncured polymer containing per molecule at least one acid group of an element selected from the group consisting of carbon, sulfur, silicon, selenium, tin, antimony, tellurium and arsenic.
