Reaktionsschritte

The procedure of Example 2 was followed using 33.9 g (0.35 mol) norbornene, 6.4 g (0.05 mol) tert-butyl acrylate, 100 mL CFC-113, 1.5 g Perkadox® 16N and 60 g (0.60 mol) of tetrafluoroethylene. The product mixture was a clear liquid which was added to excess methanol to precipitate the polymer. There was isolated 27.8 g (28%) of white polymer; GPC (MEK) Mw 11100, Mn 5600, Mw/Mn 1.99; Inh Visc. 0.0462 (MEK); Tg 130° C. Anal. Found: C, 60.39; H, 6.72; F, 28.00. 13C NMR (δ, TCB) 166 to 178 (C═O), 112 to 124 (CF2), 80 (CH), 22 to 54 (remaining carbons). From integrations of appropriate resonances, the polymer composition was found to be 36 mol % TFE, 17 mol % tert-butyl acrylate and 47 mol % norbornene.
