Abstract

MEZCLAS COMPATIBILIZADAS DE UN POLIESTER HIDROFOBICO BIODEGRADABLE, ALMIDON NO MODIFICADO U OTRO POLISACARIDO SIMILAR CONTENIENDO MENOS DE UN 1% DE AGUA EN PESO, OTROS POLIMEROS BIODEGRADABLES QUE PUEDEN SER HIDROFOBO, UN PLASTIFICANTE, Y OTROS ADITIVOS. LAS MEZCLAS SON PRODUCIDAS EN AUSENCIA DE AGUA. EL POLIMERO DE POLIESTER PREFERIDO ES POLI({EP}-CAPROLACTONA) Y EL ALMIDON PREFERIDO PROCEDE DEL MAIZ. UNA PEQUEÑA CANTIDAD DE UN AGENTE DE ESTIRAMIENTO UNICO ES INCORPORADA PARA SUMINISTRAR ALTAS ELONGACIONES EN LA ROTURA, ESPECIALMENTE EN LAS COMPOSICIONES SUPERFICIACTIVAS QUE CONTIENEN UNA CANTIDAD SIGNIFICATIVA DE ALMIDON. EL ALMIDON ES UNA FASE DISCONTINUA QUE PUEDE SER COMPLETA O PARCIALMENTE PLASTIFICADA Y EL POLIMERO DE POLIESTER ES LA FASE CONTINUA. LOS POLIMEROS PREFERIDOS TIENEN PROPIEDADES SUPERFICIACTIVAS Y SON RESISTENTES AL AGUA Y A LA HUMEDAD.
