Grafted starch

Other uses of blends include controlled rate of fertilizer release(77) based on ethylene/vinyl acetate/carbon monoxide polymers which is U.V. sensitive, polyolefin blends with any biodegradable polymers,(78) and polyolefins blended with metals and autoxidizable substrates. (79) Doane and co-workers(80) at the U.S.D.A. have used grafted starches in many applications, including soil stabilization. [Pg.9]

Avery creative application of the system HRP/H202/Acac for graft polymerization of acryl amide on starch was reported recently by Biswas and coworkers [39], Thus, a biocatalytic alternative route to the established cerium( IV)-based routes to poly(acrylate)-grafted starch with applications as superabsorbers [44] or performance additives in paper making [45] or textile sizing [46] was reported. Under non-optimized conditions grafting efficiencies of up to 65% are reported. The... [Pg.153]

The grafting of starch with more than 60 per cent of vinyl or acrylic monomers gave materials which showed excellent mechanical and processing properties, being virtually insoluble in water [61]. However, this process was deemed too expensive and thus limited the use of the ensuing grafted starch. [Pg.328]
