Abstract

Un producto de polisacáridos esterificados y el proceso para la preparación de dicho producto. El proceso puede ser enzimático, en el cual se utiliza una enzima como catalizador para la reacción. El proceso puede ser también químico, en el que no se utiliza enzima. Se obtienen novedosos productos por medio de la apertura de anillo de beta-lactona catalizada por lipasa y alcohólisis de dímeros de ceteno, también se proporciona el proceso para preparar las composiciones que contienen dichos productos. Tales polisacáridos tienen diversas aplicaciones como ser, en revestimientos, como espesante en pinturas, en materiales de construcción así como en productos cosméticos o de tocador.
