2.(10pts.) List three aspects of a polymer’s chemical structure that affect the polymer’s glass transition temperature. Describe how each aspect would alter the Tg(i.e. if x increases,Tg increases).Next, discuss the structures of polystyrene, polypropylene, and poly(ethylene glycol). How do their structures affect their respective Tg values?
