ethylene glycol structure

What Is Polyethylene Glycol?

Polyethylene glycol (PEG) is made from ethylene glycol (ethane-1 2-diol) the main ingredient in antifreeze When ethylene glycol (molecular weight 62 07) polymerizes reacts with itself (in water) the reaction yields a variety of products containing varying numbers of ethylene glycol

A new end group structure of poly(ethylene glycol) for

A new PEG end‐group structure (α‐PEG‐MA) was designed and synthesized When compared with the conventionally used PEG‐acrylate structure the vinyl group in the new structure showed comparable reactivity in thiol‐ene reactions but the formed materials were hydrolysis resistant because there is no ester linkage in the backbone chains
