✦ Synopsis

Absh act--Dilute solution properties of poly(dibenzyl itaconate) in various single and binary solvents have been studied by viscosity and gel permeation chromatography measurements. The conformational and thermodynamic parameters and flexibility factor, or, of this polymer have been determined from intrinsic viscosity, using the semi-empirical Stockmayer and Fixman equation. The results show a variation of ~, calculated on the basis of the unperturbed dimensions under 0 condition and in good solvents. The polymer-solvent interactions are discussed in relation to some other polyitaconates and polymethacrylates with the same group in the lateral chain.
