Abstract
"COPOLìMEROS DE AMINOáCIDOS E MéTODOS DE PRODUçãO DOS MESMOS". A presente invenção descreve copolímeros com base em ácido aspártico ou suas moléculas precursoras e métodos de produção dos mesmos. Os copolímeros são solúveis em água em uma grande faixa de composições e peso molecular. A preparação dos emsmos envolve a conversão de uma polisuccinimida em copolímeros de composição definida, contendo aspartato e residuos de succinimida e/ou resíduos de asparagina. Em particular, os copolímeros incluem terpolímeros solúveis em água de aspartato, asparagina e succinimida.
