Process for alkylating aromatic polyols with higher carbon number alpha olefin oligomers

A process for the alkylation of an aromatic polyol, having from 1 to 3 aromatic rings and from 2 to 4 hydroxyl groups and wherein at least two of said hydroxyl groups are directly connected to adjacent aromatic ring carbon atoms, with an alpha olefin oligomer of an alpha olefin having from 8 to 14 carbon atoms and wherein said oligomer has from 24 to 60 carbon atoms and greater than 85 percent branched olefins to produce a liquid alkyl aromatic polyol product, which comprises reacting said aromatic polyol with said alpha olefin oligomer under alkylation reaction conditions in the contact presence of a catalytic amount of an organic sulfonic acid catalyst which is soluble under reaction conditions and thereafter recovering a liquid alkyl aromatic polyol product.
