Abstract

Abstract A 1:1 copolymer of styrene and maleic anhydride has been esterified to different extents with primary alcohols R.OH and the viscosity of the esters measured in benzene and dioxan at 25°C. The intrinsic viscosity decreases and the Huggins parameter k′ increases respectively with the length of R for fully esterified copolymers and k′ increases with the extent of esterification. The roles of benzene and dioxan as good solvents for the branches and the backbone respectively are discussed.
