Abstract

The paper presents the preparation of poly(aspartic acid) (PAAs) from maleic anhydride and ammonia through a two steps reaction: first the polysuccinimide (PSI) obtainment fo lowed by the hydrolysis reaction of PSI in order to open the imide group and to prepare the polyaspartate. Poly(aspartic acid) as friendly environmental and biodegradable product can be used in pharmacy, cosmetics, agriculture, etc..

Keywords

Poly(aspartic acid), Biodegradable, Friendly environment.
