Abstract
A method for the production of a polymer material is shown and described, which is characterized by: a) producing a mixture containing at least 1 to 75 wt.-% starch and/or starch derivative, 10 to 85 wt.-% polyester, and 0.01 to 7 wt.-% of a polymer containing an epoxy group; (b) homogenizing the mixture while supplying thermal and/or mechanical energy; (c) setting the water content of the mixture, so that the end product has a water content less than approximately 12 wt.-%, in relation to the total composition of the mixture. The polymer material produced with the method according to the invention is characterized by outstanding mechanical properties.
