Versuchsvorschrift

In a 200 ml three necked flask were charged 21 g of 4-vinylpyridine, 21 g of styrene and 0.1 g of azobisisobutyronitrile and 90 ml of benzene. The mixture was polymerized at 80° C. for 6 hrs under a nitrogen atmosphere. The reaction liquid was poured into a large amount of n-hexane to thereby obtain white precipitates. After filtering and drying, a white powder was obtained. The molar fraction of vinylpyridine in the polymer was 0.57 and the yield was 20%.
