Key statement: Disclosed herein is a process for the preparation of a mixture of styrenated p-cresol species that is liquid at room temperature and has a viscosity of less than 40000 cps at 25[degrees]C, wherein said process affords 2,6-distyrenated p-cresol assaying at 70% minimum by GC area percent, comprising reacting styrene with p+cresol at a molar ratio of 1.
