Abstract
Glass transition temperatures of a very wide molecular‐weight range of ethylene oxide polymers were measured by mechanical loss and by broadline NMR. Starting at about −95°C for ethylene glycol, the glass transition rises to a maximum of −17° for molecular weight 6000 and then drops off to −53° for polymers with molecular weights greater than 200 000. This unusual behavior is probably caused by the high crystallinity of the intermediate molecular‐weight polymers.This publication has 14 references indexed in Scilit:
