Vorkapic, D, Matsoukas, T, "Reversible Agglomeration: A Kinetic Model for the
Peptization of Titania Nanocolloids.
The
peptization of units and the increase of aggregate stability of suspensions can be observed.
When a low surface area adsorbent (the red or yellow dispersant) is present, an excess of the triblock in the aqueous phase builds, and the interaction of the oxyethylene units with the talc surfaces begins a
peptization of large platelet aggregates that results in an increasingly competitive adsorbent surface area to the colorant's surface area.
The 300% modulus, being a measure of strain-induced crystallization, responds to higher degree of
peptization.

Peptization 2.
Liquid polysulfide polymers, such as the Thiokol LP series (Morton International), are also able to form reactive crosslinking short chains through accelerator
peptization of the sulfurs in the polymer chain.
