    Abstract: Molybdenum compounds, particularly molybdenum sulfide, molybdenum silicide, molybdenum selenide and molybdenum telluride are useful Friedel-Crafts catalysts for the aralkylation of aromatics to produce polybenzyls, the manufacture of aromatic ketones, aromatic sulfones and aromatic esters.The foregoing processes are carried out at a temperature of about 60.degree. to 250.degree. C. and at a catalyst concentration of about 0.1 to 15% by weight of reactants. The reaction products are useful as laminates, herbicides and bactericides.

    Abstract: This invention relates to copolyimides-polyamides prepared from mixtures of tetramethylcyclobutane-1,2,3,4-tetracarboxylic dianhydride (TMCDA), aromatic or aliphatic dianhydrides, and dicarboxylic acids or their esters or acid chlorides. These dianhydride-dicarboxylic acid mixtures are then reacted with aliphatic or aromatic diamines. These novel copolyimides-polyamides are useful in the preparation of molded articles, fibers, films, laminates and coatings.
