Polymer PEG (Polydisperse PEG)
Polymer PEG is a Polyethylene glycol (PEG) polymer with an averaged molecular weight, such as 2K, 5K,
10K, 20K with PDI ranging from 1.01-1.10. Polymer PEG is also known as polydisperse PEG, or Poly-PEG.
There are different shapes of Polymer PEG, such as linear, Y-shaped, branched, or star shaped with
different PEG chain lengths as shown in Figure 1. PEG chain can be attached with different functional groups
for chemistry modification and industrial application.
Figure 1. Examples of Polymer PEG that are commercially available. Typical functional groups include
Acrylate, alkyne, Amine, Azide, DBCO, TCO, Aldehyde, Acid, NHS ester, Hydrazide, Maleimide, Silane,
Biotin, Tos, or Thiol.
Polymer PEG have become especially attractive tools in various pharmaceutical, biological and chemical
industry application due to its aqueous solubility, high flexibility and non-immunogenicity
Polymer PEG, Acrylate
PEG-acrylates contain vinyl groups (-CH=CH2) which can be used for radical polymerization with initiator
under heat or UV light. The common radical polymerizations include atom transfer radical polymerization
(ATRP), free radical polymerization (FRP), and reversible addition-fragmentation chain transfer (RAFT)
polymerization. PEG -acrylates can also be used for thiol-ene reaction in the presence of UV light.
