| Hazard Information | Back Directory | [Chemical Properties]
clear liquid | [Uses]
2-Ethyl-2-oxazoline (EtOx) was used in synthesis of block copolymers of EtOx and styrene by cationic ring-opening polymerization and atom transfer radical polymerization. | [Uses]
2-ethyl-2-oxazoline is an organic intermediate and monomer that is used in water-soluble polymers, pharmaceuticals, cosmetics, specialty coatings and adhesives. | [General Description]
2-Ethyl-2-oxazoline undergoes cationic ring opening graft polymerization using tosylated cellulose nanowhisker as macroinitiator. | [Flammability and Explosibility]
Notclassified | [Toxics Screening Level]
This value was used as a surrogate inhalation LC50 to calculate an acceptable ambient concentration (AAC) since other adequate toxicity data were not available, At 25°C and atmospheric pressure the AAC of 0.013 ppm is equivalent to 53 μg/m 3. |
