Polymer blends of chitosan (CS) and poly(sodium-4-styrene sulphonate) (PSS) have been compatibilized
using lysine (LYS) and glutamic acid (GLU). Blends of CS/PSS containing LYS and GLU have been studied
by thermal analysis. The values of Tg for CS/PSS-LYS blends could not be detected by thermal analysis but
one single Tg
