Environmentally friendly, biodegradable biopolymers can be prepared via the chemical modification of starch. These are able to partially or totally substitute synthetic additives used today in environmental technologies. Through building ionic function groups into polymeric chains starch ion exchangers, flocculants dispersants produced. In this paper, we examine water-soluble derivatives called polyelectrolytes. By phosphorylating while preserving maybe increasing molecular weight native polymers, anionic flocculating agents prepared. If polymer degrade during reaction, products will act as dispersing aqueous suspensions. It is apparent that, phosphorylation changes distribution and charge polymers have crucial importance. our experiments, investigated solid-phase reactions by following change distributions, using size exclusion chromatography, densities, a particle detector. The efficiency was tested laboratory, results were evaluated means severity parameters.
