Abstract:
A method for manufacturing a thermoplastically processable polymer composition comprising:(a) blending at least one of starch or a starch derivative with at least one hydrophobic material selected from the group consisting of esters, lactones, polyesters, esteramides, polyesteramides, dimeric fatty acids, modified fatty acids, acid methyl esters, esterpolyols, polyesterpolyols, glycerol trioleate, glycerol dilinoleate, and mixtures thereof, and(b) mixing and heating the starch or starch derivative with the hydrophobic material in a manner so as to form a thermoplastic melt and in order for at least a portion of the starch or starch derivative to react with at least a portion of the hydrophobic material so as to form at least one condensation reaction product of the starch or starch derivative and the hydrophobic material and in order to thereby form the thermoplastically processable composition.
