Procedimiento

The compound phenoxyethylvinylether is prepared by reacting chloroethylvinylether with sodium phenate, followed by polymerization in dichloromethane initiated with TiCl4 at -10° C. By reacting 8.2 g of the polymer with 9.8 g of phenyliodosotoluene sulfonate in 40 mL of a mixture of an equal volume of acetic acid and dichloromethane. A polyiodonium is obtained which is precipitated with ether. The ionic exchange reaction is carried similarly to that of example 3 between 12 g of polymer and 7 g of sodium bis(trifluoromethanesulfonyl)imide. After precipitation and washing with water, there is obtained a sticky mass which is used in a 50% solution of methylethylketone.
