Chinese name: 4-arm polyethylene glycol amide succinic acid, 4-arm peg amide succinic acid.
English Name: 4-arm-peg-saa
Xi'an Kaixin Biotechnology***
Appearance and properties:
4-ARM-PEG-SAA, 4-arm PEG amide succinic acid, consists of polyethylene glycol (PEG) and SAA linked by ester bonds. This polymer can self-assemble in an aqueous solution to form micelles.
Synthesis of polymers: The synthesis of PEG-SAA requires the use of azodiisobutyronitrile (AIBN) as a free radical initiator, N,N-dimethylformamide (DMF) as a solvent, and N-bromosuccinimide (NBB) as a bromination reagent. First, dissolve PEG and PEG-SAA in DMF and stir well at 70 °C. Next, add PEG-SAA and NBB to the solution and continue stirring until completely dissolved.
