Abstract
Chloro-terminated polysulfones with various molecular weights were che mically modified with bis(2,4-dihydroxybenzaldehyde)copper(II). The pr operties of modified polysulfones are compared with the unmodified one s, and an increase in glass transition temperatures, softening points and reduced viscosities of the former materials was observed. In addit ion, the chelate-modified polymers exhibited excellent thermal stabili ty properties and semicrystalline patterns. Also, they provided transp arent and flexible films.
