Destructurized starch and method of making same.

摘要

A thermoplastic melt made from starch containing bound phosphate groups and having a water content of 5 to 30% by weight calculated to the starch/water composition characterized in that within said melt the relative concentrations of the cations and the protons bound to said phosphate groups are within the limits eq.M<2><+> : M<+> : H<+> = (0.0-1.9) (0.0:0.9) : 0.0-1.4) wherein M<2><+> is a divalent cation, preferably Ca<2><+> or Mg<2><+> or a mixture of these cations; M<+> is a monovalent cation, preferably Na<+> or K<+> or a mixture of these cations; H<+> is the proton and the sum of the numbers of said equivalents eq.M<2><+>, M<+> and H<+> per mole of phosphate groups equals 2.
