Abstract
A method for obtaining an improved plasticized material results from two differentiated steps: an esterification reaction for synthesizing a polycarboxylic acid ester oligomer in the presence of excess polyol and a catalyst, and a second step of gelatinization and plasticization at temperatures above 90° C. involving a starch mixed with water and with the polycarboxylic acid ester oligomer with excess polyol obtained in the previous step, and a coadjuvant. The catalyst used in the esterification reaction is the same as the coadjuvant used in the gelatinization and plasticization reaction. The plasticized material obtained with this method has a higher stability and a lower migration rate than known plasticized materials.
