Reaktionsschritte

3,4; 5,6 -tri - 0 -(p-vinylphenylboronate), 12 ml acetonitrile, 4 ml methylmethacrylate 5.3 ml glycoldimethacrylate, and 75 mg azoisobutyronitrile (A I B N) are polymerized as described in example 1. The D-mannitol of the produced polymer is dissolved by treating the polymer in a column at 50° with a mixture of methanol/water 1:1. After eluting with 2 l of solvent during 24 hours more than 80 percent of D-mannitol are removed from the polymer. The polymer shows a good resolving power for the racemate D,L-mannitol. Furthermore one obtains good chromatographic separations between mannitol, sorbitol and dulcitol.
