Reaction Steps

Aqueous Dissolution of 2-(4-Silyloxymethyl-Phenoxy)-Ethyl Vinyl Ether/Maleic Anhydride Copolymer--A slurry was made with 20 g of 2-(4-silyloxymethyl-phenoxy)-ethyl vinyl ether/maleic anhydride copolymer in 498 g of distilled water. To this was added 108 g of a 20% aqueous NaOH solution. The slurry was heated to 75° C. for 48 hours. The reaction was then cooled to room temperature to give a 3.37% concentrated solution of 2-(4-hydroxymethyl-phenoxy)-ethyl vinyl ether/maleic diacid at pH 12.7.
