Description

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
