摘要：
The invention is directed to a method for preparing an environmentally degradable polymeric compound as well as to such a compound per se and to its use. A compound of the present invention includes a polycondensated lactic acid containing polymer, having a molecular weight (Mw) of from 500 to 50,000 g/mol, to which a flexibilizing aliphatic polyester having a molecular weight of from 500 to 50,000 g/mol is coupled. The amount of lactic acid including groups in the polymeric compound ranges from 50 to 99% and the amount of flexibilizing polyester groups ranges from 1 to 50%.
