mixing 1800 0 parts of this mixture was reverse thinned into 1497 8 parts of agitated deionized water an additional 347 1 parts of deionized water was added to yield a homogeneous dispersion which evidenced a solids content of 39 2 after 1 hour at 110 u00b0 c a mixture of 819 2 parts of bisphenol a diglycidyl ether eew 188 263 5 parts of bisphenol a and 209 4 parts of 2 n butoxy 1 ethanol was heated to 115 u00b0 c at that point 0 8 parts of ethyl triphenylphosphonium iodide was added this mixture was heated and held at a temperature of at least 165 u00b0 c for one hour as the mixture was allowed to cool to 88 u00b0 c 51 3 parts of ektasolve eeh solvent and 23 2 parts of 2 n butoxy 1 ethanol were added at 88 u00b0 c a slurry consisting of 32 1 parts of 85 o phosphoric acid 18 9 parts phenylphosphonic acid and 6 9 parts of ektasolve eeh was added the reaction mixture was subsequently maintained at a temperature of at least 120 u00b0 c for 30 minutes at that point the mixture was cooled to 100 u00b0 c and 71 5 parts of deionized water.
