Aquazol®

Poly(2-ethyl-2-oxazoline)

A High Performance Water-Soluble Polymer

Aquazol, poly(2-ethyl-2-oxazoline) – also known as PEOX or PEtOx, is a unique and innovative water-soluble polymer which is non-toxic, non-hazardous, and biocompatible. Among other novel characteristics, this polymer is temperature responsive and inversely soluble above its LCST, ~66°C.

Aquazol’s numerous advantages come from its unique design, featuring a stable amide group (found in natural proteins), with the amide nitrogen in the backbone of the polymer and the amide carbonyl group in the dangling side chain. The doubly bonded, electronegative oxygen in the carbonyl is structurally positioned to readily hydrogen-bond. This novel and innovative design of the polymer backbone presents many advantages over other in-class polymers (PVA, PEG, PVP), including:

  • Increased Stability under Temperature, Shear, Oxidation, and UV
  • Unparalleled “Actives” Loading Capability
  • Incredibly Broad Solubility
  • Precise Control of Viscosity
  • Excellent Film Forming
  • No “Unzipping Mechanism” and No Rapid Off-Gassing
  • Strong Adhesion
  • Impressive Compatibility
  • Especially Broad Dispersity
  • Ease of Processing

Product Specifications

Aquazol is supplied as 100% active off-white amorphous granules in four different grades, all having a poly-dispersity range of 3 – 4. Aquazol grades are based on kinematic viscosity, as detailed in the table below:

Product
Grade
Kinematic Viscosity Range
(10% Aqueous Solution)
Aquazol 5 2 – 3 cSt
Aquazol 50 5 – 7 cSt
Aquazol 100 18 – 24 cSt
Aquazol 500 60 – 80 cSt

For Aquazol polymer with a narrow pdi (<1.9) and targeted molecular weight, please inquire about HP Aquazol.
