Procedure

In 800 g of xylene, 1641 g (2.2 moles) of dibehenyl itaconate of the formula, C22H45OCOCH2C(═CH2)COOC22H45, obtained by a reaction between behenyl alcohol and itaconic acid, and 875 g (1.0 mole) of the organopolysiloxane having mercapto groups at both terminals represented by the following formula were reacted in the presence of 1 g of triphenylphosphine as a catalyst at 130° C. for 5 hours. 2440 g, corresponding to a yield of 97%, of Silicone wax (H) was obtained by stripping the solvent.
