523 tradename for a partially hydrolyzed polyvinyl alcohol of approximately 77 000 to 79 000 molecular weight commercially available from air products inc and 2636 4 grams of deionized water with agitation concentrated ammonium hydroxide was added to the mixture until a ph of 7 0 was achieved to the solution were added 3 7 grams of lucidol 70 tradename for a 70 active benzoyl peroxide commercially available from lucidol division penwalt corporation followed by the addition of 1000 grams of 2 ethylhexyl acrylate monomer a vacuum was then drawn upon the contents of the flask the pressure therein being drawn to approximately 25 inches of mercury and maintained while stirring for approximately 5 minutes to assure removal of dissolved air and oxygen the vacuum was then broken with nitrogen and a nitrogen purge was maintained throughout the reaction period which follows added to the mixture were 21 5 grams of trycol oal 23 tradename for an oleyl alcohol ethoxylate nonionic surfactant commercially available from emery industries inc and the agitation rate was set at 300 rpm the batch was then heated to 60 u00b0 c as the temperature initially approached 60 u00b0 c a mild exotherm was noted which raised the temperature to approximately 70 u00b0 c approximately 2 25 hours after the batch hit 60 u00b0 c the batch.
