Versuchsvorschrift

BuNB (25.44 g, 0.169 mol), Norbornenylethyltrimethoxysilane (TMSENB, CAS 68245-19-2) (4.56 g, 0.019 mol), triethyl silane (0.11 g, 9.41E-04 mol), ethanol (0.10 g, 2.26E-03 mol) and toluene (170.0 g) were combined in a 300 mL serum bottle and heated to 80° C. in an oil bath to form a solution. To this solution were injected Pd1446 (0.022 g, 1.50E-05 mol) and DANFABA (0.036 g, 4.51E-5 mol), each in the form of a concentrated solution in dichloromethane. After addition, the resulting mixture was maintained at 80° C. for 4 hours. The copolymer was precipitated by adding methanol drop wise into the vigorously stirred reaction mixture. The precipitated copolymer was collected by filtration and dried in an oven at 60° C. under vacuum. After drying, 22.60 g was obtained (69%). The molecular weight of the copolymer was determined by GPC in THF solvent (polystyrene standard) to be Mw=20,000 and Mn=13,000. The composition of the copolymer was determined by 1H-NMR to be (91/9) BuNB/TMSENB copolymer. The refractive indices of this polymer were measured by prism coupling method and determined to be 1.5106 in TE mode and 1.5105 in TM mode at a wavelength of 633 nm The dried copolymer was dissolved in sufficient toluene to result in a 30 wt % copolymer solution.
