    Abstract: The present invention relates to a thermoplastic composition, in particular for use in extrusion and compounding, having a continuous phase, which comprises at least one first polymer, which is selected from a group comprising a polyester, a polyesteramide, a polyesteretheramide, an aliphatic or partially aromatic polyester urethane or mixtures thereof, in particular such compounds or mixtures having hydrophobic surface properties, and at least one dispersed phase, which, as the second polymer, comprises at least one biogenic crosslinking agent having a water content of 0.1 to 30 wt. %, in particular 5 to 25 wt. %, with reference to the total weight thereof, and wherein the first polymer of the continuous phase is not miscible with the second polymer of the dispersed phase, and has at least one inorganic filler, and at least one plasticizer. The composition according to the invention is characterized in that it has the plasticizer diglycerol or mixtures with diglycerol, and the filler is in a proportion of 0.1 to 40 wt. % with reference to the total weight of the composition.

    Abstract: Provided is a resin composition comprising a starch and a polyvinyl alcohol, which is excellent in the breaking strength and breaking elongation at a low temperature, and at the same time, has the good gas barrier property. The resin composition comprises modified starch and polyvinyl alcohol, and where in a cross section photograph by a transmission electron microscope, a cross-sectional area of each of particles of the polyvinyl alcohol dispersed is calculated, and a cross-sectional shape of each of the particles of the polyvinyl alcohol is postulated to be circular based on the cross-sectional area, the particles of the polyvinyl alcohol have a conversion particle diameter of 50 to 300 nm, and the conversion particle diameter has a dispersity of 3.0 or less.
