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
