Abstract

The invention relates to a process for thermoplasticizing starch, to a melt-workable polymer composition containing a starch-based component and a thermoplastic polymer component and to a process for producing such a composition. According to the invention, the starch is firstly modified such that it dissolves in a hydroxyacid polymer melt. At the same time, care is taken to ensure that the modified starch still contains free hydroxyl groups which can react with isocyanate groups. The modified starch is then reacted with a thermoplastic component consisting of a hydroxyacid polymer, in particular of a lactic acid polymer, resulting in a melt- workable, biologically degradable starch-based polymer which can be used as a binding agent for coating both paper products and cardboard products.
