CA 2207597

A method for improving the extrusion characteristics of finely divided aqueous starch-polymer mixtures comprising subjecting the admixture to de-aeration and compaction to form a hard shaped form therefrom, milling the hard shaped form of starch and polymer admixture to form granules. Granules of selected size are then coated with a lubricating compound.

Selon un procédé d'amélioration des caractéristiques d'extrusion de mélanges aqueux d'amidons et de polymères finement divisés, on désaère le mélange et on le comprime jusqu'à obtenir un corps façonné solide, on broie le corps façonné solide en mélange d'amidon et de polymère jusqu'à obtenir des granules et on enrobe les granules ayant une taille sélectionnée d'un composé lubrifiant.
