11. 2. The reaction mixture was kept for 20 h at room temperature. Polymerisation was stopped by adding 50 equiv. of ethylvinylether . After 30 min the reaction mixture was slowly added to vigorously stirred methanol. After reprecipitation and drying in vacuum poly2 was isolated with the yields given in Table 1.
