Procedure

Following the procedure of Example 46, hydroxy-terminated methyl methacrylate (35%)/n-butyl methacrylate (BMA) (65%) copolymer was prepared using the following amounts of materials: [(2-methyl-1-[2-(trimethylsiloxy)ethoxy]-1-propenyl)oxy]trimethylsilane, 0.51 g (1.85 mmol); MMA, 11 ml (103.7 mmol); BMA, 30 ml (188.5 mmol); tris(dimethylamino)sulfonium bifluoride, 20 mg (0.1 mmol); THF, 100 ml. Upon addition of the monomers the temperature rose to 48.6° from 20.6°. Evaporation of solvents and drying of the resultant residue gave 38.6 g of copolymer. GPC: Mn 22100, Mw 24500, D 1.11 (theor. Mw 20,215).
