There is a class of polyesters that have the general structure shown below. For example, in polyethylene terephthalate (PET) m =1. How would you expect the Tg ad Tm of these polymers to vary with m, given that the molecular weight of the chain is held constant? Give reasons for your answer. Also, assuming that you are now just considering one member of this class of polymers, say PET, how does the Tg vary with molecular weight, n.
