Application
Poly(ethylene glycol) methyl ether can be used:
- As a chain transfer agent to synthesize amphiphilic block copolymers by metal-free ring-opening oligomerization.
- As a precursor to prepare retinoic acid-polyethylene glycol nanoassembly as an efficient drug delivery system.
- To prepare diblock copolymer with polylactic acid, which can be applied in the field of tissue engineering and drug delivery.
