Procedure

The copolymer of allyl methacrylate and methacrylate was prepared by placing 5 grams of allyl methacrylate, 95 grams of methyl methacrylate, 300 milliliters of methylene chloride, and 1.0 gram of isopropyl peroxydicarbonate in a 28 ounce round bottle. The bottle was sealed. The bottle was then heated at 50 degrees Centigrade in a water bath for 18 hours. The bottle was then removed from the water bath, and the polymer isolated by extraction with methanol to precipitate polymer. The polymer was then dried under vacuum. Thereafter, the molecular weight was determined by inherent viscosity in methylene chloride versus poly(methyl methacrylate), and was found to be in excess of 500,000.
