Abstract: Novel homopolymer and copolymer compositions produced from the polymerization of non-conjugated dienes have been discovered. The novel compositions are produced by an equally novel process comprising cyclopolymerization of non-conjugated dienes employing reduced valence state Group VIB metal oxide catalyst on porous support. The preferred catalyst comprises carbon monoxide reduced chromium on silica. Copolymers are formed by copolymerization of non-conjugated dienes with 1-alkenes in contact with the activated chromium on silica catalyst. The compositions are useful as lubricants and additives.

Abstract: A catalytic process for the dimerization of norbornene and/or norbornadiene using a reduced valence state Group VIB metal oxide as the catalyst, preferably Cr(II) on a porous support such as silica. The product norbornene dimer or norbornadiene dimer is obtained in high yield and high stereospecificity at greater than 90 weight percent of the exo-trans-exo stereoisomer. The norbornene dimer is useful as a high energy density fuel. The norbornadiene dimer can be further functionalized to yield novel chemical intermediates or polymerized or copolymerized with other olefins. The norbornadiene dimer can also be hydrogenated for high energy fuel applications.

Abstract: Long chain alkyl aromatic compounds are prepared by alkylating an alkylatable aromatic compound with a long chain alkylating agent in the presence of a catalyst comprising an acidic solid material which comprises a Group IVB metal oxide, such as zirconia, modified with an oxyanion of a Group VIB metal, such as tungstate.

Abstract: A process for the heterogeneous catalytic oligomerization of norbornene comprising the steps of reacting norborene in the presence of a solid catalyst comprising a porous crystalline material having a Constraint Index of from about 0.1 to about 12 under oligomerization conditions to evolve a product containing norbornene oligomers.

Abstract: A process is disclosed for the catalytic norbornylation of aromatics comprising the steps of contacting norborene and an aromatic hydrocarbon with a solid catalyst comprising a porous crystalline material having a Constraint Index of from about 0.1 to about 12 under norbornylation conditions to evolve a product containing norbornylated aromatics.

Abstract: There is provided an oligomerization process. The process involves the use of a catalyst comprising an acidic solid. The acidic solid may comprise a Group IVB metal oxide, such as zirconia, modified with an oxyanion of a Group VIB metal, such as tungsten. The oligomers produced by this process may be hydrogenated to produce thermally stable lubricants and lubricant additives.
