Abstract: The invention relates to a biodegradable, thermoplastic molding material that contains a) at least one biodegradable, thermoplastic copolyester and b) 0.01 to 15 % by weight of a hydrophobically modified phyllosilicate, based on the entire weight of the thermoplastic molding material. The invention further relates to a method for producing the molding material and to molded bodies, films and fibers produced from said molding material.

Abstract: The invention relates to a continuous method of incorporating at least one solids powder A into a melt containing at least a thermoplastic polymer B, in an extruder. The polymer B is fed into the extruder at one end either in the form of granules which are then melted in the extruder or in the form of a melt, and the solids powder A is fed into the extruder at the same point and/or downstream of the point at which the polymer B is fed into the extruder. Downstream of the feed-in point(s) of A and B water is injected into the extruder.
