Abstract
A thermoplastic polymer composition comprising: (a) a destructurized starch, and either (b) an effective amount of at least one compound selected from the following: (1) a polymer which contains at least two different types of functional groups, one of said types of these groups being hydroxyl groups; (2) at least one polymer which does not contain hydroxyl groups and is selected from the group consisting of polymers which contain at least two types of functional groups bound to the same molecule one type of these groups being carboxylate groups; (3) at least one polymer selected from the group consisting of polymers which contain tertiary amino groups and/or salts thereof and/or quaternary ammonium groups; (4) at least one polymer selected from the group of polysaccharides which have been chemically modified to contain added hydroxyalkyl groups and/or contain alkyl ether groups, and/or contain ester groups; (5) at least one compound selected from the group consisting of copolymers of vinyl pyrrolidone; (6) at least one compound selected from the group consisting of cationically modified polysaccharides; (7) at least one compound selected from the group consisting of anionically mo…
