Application:	1,2-Epoxybutane can be used: • As a monomer to synthesize novel initiators via ring-opening polymerization. These initiators can be used to prepare complex macromolecules such as grafted polyamides. • To functionalize polyethyleneimine which is used in the synthesis of oxidation-stable adsorbents for CO₂ capture.
Features and Benefits:	• High polymerizability • Low susceptibility to transfer reaction • Ease of handling
