Abstract

Environment-friendly polyhydroxy carboxylic acid and acid salt polyelectrolytes are prepd. by partial hydrolysis and oxidn. of p;ysaccharides. This is carried out with HNO3 mixt. of H3NO3 and H2SO4, H2O2, sodium hypochlorite or other oxidising agents. The choice of type and concn. of oxidising agent does not only influence the rate of reaction but also the relative proportions of polyhydroxy-polycarboxylic acids formed, significant in intended applications.
