Versuchsvorschrift

instead of aluminum isopropoxide, 0.8 g of tetrabutyl zirconate (as a 30% solution in xylene) is added to the 2,4-dimethylphenol. Butyl alcohol and xylene are removed with heat and vacuum to yield zirconium 2,4-dimethylphenoxide, which upon addition of toluene and divinylbenzene and reaction in accordance with part A of Example I, functions as an alkylation catalyst, yielding a similar yield of the same styryl monomer.
