    • Typically, poly(ethylene glycol) refers to polymers with molecular weights below 20 000 and poly(ethylene oxide) refers to higher molecular weights above 100 000. The upper molecular weight limit for polyethylene glycoDs is due to side reactions during the industrial scale base-catalyzed polymerization of ethylene oxide; see ref 1.

    • Another explanation for the non-Gaussian molecular weight distributions is that the monomers were forming homopolymers rather than copolymers. However, this is less likely because the Tg scale proportionally between those of the two homopolymers (-59.0 °C for 11 and 24.5 °C for 13e) as one would expect for the copolymers.
