Procedure

Analogously to the procedure described in Example I, 0.285 g of the polymer prepared according to Example 16 and having a palladium content of 18.5% by weight, are warmed to 60°-65° C. with 12.2 g of benzoic acid and 55.4 ml of vinyl acetate. After 29 hours, 11.3 g of vinyl benzoate have formed, corresponding to a yield of 76% of theory. Using the recovered catalyst, 10.4 g of vinyl benzoate, corresponding to 70.5% of theory are again obtained after 20 hours in a further reaction batch.
