Procedure

Next, 210 g of methyl methacrylate (MMA) and 90 g of butyl acrylate (BA) were added to the aqueous solution to dissolve the silicone resin precipitate therein whereupon the MMA/BA solution of the silicone resin was isolated from the water layer. To the isolated solution was added 500 g of water. The mixture was thoroughly agitated and mixed for 10 minutes and allowed to stand whereupon the water layer was separated. The amount of methanol contained in the organic layer was determined by GC, detecting 0.2% by weight in the solution. There was eventually obtained 505 g of a MMA/BA solution having a nonvolatile content of 40.2% by weight (105OC/3 hours), designated Solution A.
