✦ Synopsis

Intrinsic viscosity, light scattering, and sedimentation data are reported for fractions of polytert.butylacrylate in different solvents and in a 0-solvent. The unperturbed dimension has been calculated by various methods; the Stockmayer-Fixman and Kurata-Stockmayer relationships gave the best fit for the experimental results in the different solvents; the flexibility (o) of the chains has been found to be between 2.2 and 2.3; this value seems to be indicative of an influence of the bulky side group.
