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

Ethylene oxide and 1,2-butylene oxide were sequentially polymerised to form the diblock copolymer E13B10 (E=oxyethylene, B=oxybutylene, subscripts denote number-average block lengths in repeat units). Dynamic and static light scattering over the temperature range 10-30 degrees C demonstrated a transition from
