I'll consider these three things you've mentioned. Size of side groups: PE has very small side groups in the H atoms, while PEG has no side groups on the O. This would imply that PE might have slightly more hindered rotation, meaning a higher glass transition than PEG, however this is not...

Thank you both, I get it now. Should have remembered the stability vs. electronegativity thing.

Does that mean C-O bonds don't rotate as freely as C-C bonds, maybe an inequality in the electronic character of the C and O atoms that causes stiffness?

Can anyone tell me why poly(ethelyne glycol) has a higher Tg than polyethylene?

Can anyone explain concisely why Trifluoroacetic Acid is more acidic than Trichloroacetic Acid, but HCl is more acidic than HF?
