Abstract
Maleic anhydride-monooctyl itaconate copolymer was synthesized by radical polymerization. The viscometric behaviour was studied in dilute solution. The copolymer was fractioned and characterized by size exclusion chromatography membrane osmometry and viscometry. The classical viscometric relationships were established in several solvents. The conformational and thermodynamic parameters K θ and B were evaluated from viscosity data in good solvents using the Stockmayer Fixman, Berry and Kamide-Moore extrapolations. The rigidity parameters σ and C ∞ show flexibility of the polymer chain, due to the incorporation of the maleic anhydride units when the copolymer is compared with the corresponding homopolymer poly(mono-n-octyl itaconate).
