Polymer material and method for the production thereof

摘要

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.

1. Method for producing a polymer material containing starch, comprising:
(a) producing a mixture comprised of:
1 to 75 wt. % of starch and/or starch derivative;10 to 85 wt. % of polyester; and0.01 to 7 wt. % of an epoxide group-containing polymer; (b) homogenizing the mixture by supplying thermal and/or mechanical energy; and (c) removing water by degassing the mixture during homogenization of the mixture to reduce the water content of the mixture, so that the end product after mixing has a water content of less than 1.5 wt. % based on the total composition of the mixture.
