Abstract
"PROCESSO PARA PREPARAçãO DE POLìMEROS E RESINAS BIODEGRADáVEIS A PARTIR DE PROTEìNAS E POLìMEROS OBTIDOS ATRAVéS DE PROCESSO PARA PREPARAçãO DE POLìMEROS E RESINAS BIODEGRADáVEIS A PARTIR DE PROTEìNAS". Compreendendo um método para preparar polímeros, resinas e plásticos de poliéster/poliamida a partir de proteínas. Usando ácido nitroso ou óxido nitroso, uma proteína é convertida em um protómero de hidroxila carboxila poliamida. Protómeros são condensados através de grupos hidroxila e carboxila para fazer ligações éster interprotómero, resultando em um polímero, resina ou plástico de poliéster poliamida.
