Versuchsvorschrift

Copoly(N-vinyl carbazole-vinyl acetate) (5.0 g) was dissolved in 100 ml of tetrahydrofuran and 25 ml of I N methanolic sodium hydroxide was added. The solution was stirred for 3 hours at 60° C and precipitated into 600 ml of methanol. The polymer was purified by two additional precipitations from tetrahydrofuran into methanol. The purified polymer was obtained in 90% yield and was found to contain 46.6 mole percent N-vinyl carbazole (calculated from nitrogen analysis).
