                 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

                Alkyne-attached PEG polymer can react with azide group via Cu catalyzed click chemistry which generates  
                a stable triazole bond. The click chemistry has profound impacts on polymer and materials science,  
                chemical biology and drug discovery, bioimaging, and more.

                             Amine Alkyne-PEG-OH, MW 2,000 is a PEG polymer derivative with three reactive sites. The polymer is  
                            used for coupling with NHS ester. It is also azide reactive to form a stable triazole bond. The hydroxyl group  
                            can further derivatize to other molecule.
