Behavior of Ternary Mixtures from Maleic Copolymers, Collagen and Chromium Ions

摘要

The ability of polyelectrolytes to interact with globular proteins forming stable protein-polyelectrolytes complexes (PPC) is well know. The main challenge in the leather industry is to provide high quality products ensuring at the same time the protection of the environment. The interaction of maleic acid copolymers with collagen hidrolyzates in presence or in absence of chromium ions were studied by potentiometric, conductometric and turbidimetric titrations.
