MONOESTERIFICATION OF STYRENE-MALEIC ANHYDRIDE COPOLYMERS WITH ALIPHATIC ALCOHOLS

Maleic anhydride - styrene copolymers were synthesized in acetone-toluene solution at 60° C by azo-bisisobutironitrile. The copolymers were characterized by Gel Permeation Chromatography and Differential Scanning Calorimetry. The monoesterification of the maleic anhydride-styrene copolymers was carr...
