Poly(dextran-g-acrylamides) from ferrous ion—hydrogen peroxide initiation Graft copolymerization of acrylamide onto dextran with ferrous ion-hydrogen peroxide initiation is being studied in detail. The effect of variation of each reaction parameter on graft copolymerization behavior may be measured by direct gel permeation chromatographic analysis of the final product polymer solution. 

The number of the branch PMMA chain per one molecule of of dextran was 0.05-0.3 for M 6,000 of the dextran (d1), 0.35 0.55 for P 61,000 (d2), and 0.8-1.6 for M 196,000 (D3), respectively. If some information are given from matrix molecule (backbone polymer) to the resultant pol3nner (the branch polymer), it may be very important to solve the template reaction of nucleic acid (DNA, RNA) in biosynthesis. These graft pol3nnerization of vinyl compounds onto water-soluble polysaccharides must be consequence from this point as same as matrix polymerization by Kargin et al.. As seen in Fig. 10, with the sample of D1 and D2, the plot of In(lOO-i) ) versus time (t) gave the straight line in accordance with the equation ...
