POLYASPARTATES: BIODEGRADABLE ALTERNATES TO POLYACRYLATES OR NOTEWORTHY MULTIFUNCTIONAL INHIBITORS?

摘要

Polyaspartates have been compared to phosphonates and polyacrylates in order to evaluate their efficiency as corrosion and calcium carbonate scale inhibitors and also as dispersive agents. This evaluation shows that polyaspartates may be considered as multifunctional inhibitors. Microvision experiments confirm nevertheless that they have some similitudes of action with polyacrylates particularly concerning scale inhibition and protective film formation.
