Abstract

Complejos estequiométricos del ácido poli({ga}-glutámico) y tensioactivos catiónicos. Complejos preparados a partir del ácido poli({ga}-glutámico) de biosíntesis y bromuros de alquiltrimetilamonio con grupos alquilos lineales de hasta 22 átomos de carbono, insolubles en agua y solubles en disolventes apolares, capaces de adoptar estructuras bifásicas en estado sólido con la fase parafínica cristalizada a temperatura ambiente para cadenas alquílicas de longitud igual o superior al octadecilo. Todos ellos capaces de formar películas transparentes, resistentes y térmicamente estables hasta temperaturas por encima de 240ºC con plasticidad modificable por calentamiento a temperaturas por debajo de los 80ºC. Palabras claves: Ácido poli({ga}-glutámico), tensioactivos catiónicos, complejos poliméricos iónicos, polímeros peine.
