In a process for producing a methyl-substituted biphenyl compound, at least one methyl-substituted cyclohexylbenzene compound of the formula: wherein each of m and n is independently 1, 2, or 3, is contacted with hydrogen in the presence of a hydrogenation catalyst to produce a hydrogenation reaction product comprising at least one methyl-substituted bicyclohexane compound, and the methyl-substituted bicyclohexane compound is then contacted with a dehydrogenation catalyst to produce a dehydrogenation reaction product comprising at least one methyl-substituted biphenyl compound.

Production of methyl-substituted biphenyl compounds

A polyacrylate-polyolefin copolymer and composition for volatile solvent-free coating comprising such compounds having the following structure: wherein 'PO' is a polyolefin having a number average molecular weight of at least 300 g/mole, and 'Ar' is selected from the group consisting of C6 to C20 aryls, a C7 to C32 alkylaryls, a C6 to C20 aryloxys, and halogen substituted C6 to C20 aryls and C7 to C32 alkylaryls, while the other variables are as described herein. The copolymers can be produced in an alkylation reaction between the desired polyacrylate and a vinyl/vinylidene-terminated polyolefin.

Copolymers

A composition is described comprising a mixture of (methylcyclohexyl)toluene isomers having the following formula: wherein the mixture comprises at least 50 wt % in total of the 3,3, 3,4 4,3 and 4,4-isomers of (methylcyclohexyl)toluene.
