Abstract
The dilute solution properties of six near-monodisperse samples of poly(tert-butyl methacrylate) covering the molecular weight range {Mathematical expression} are reported. Unperturbed chain dimensions were derived from a combination of light scattering and intrinsic viscosity data. A characteristic ratio (C∞) of 12.0 was obtained in the theta solvent cyclohexane at 10°C. This C∞ value is considerably larger than the value of 8.8 reported previously for poly(n-butyl methacrylate) and reflects the greater bulkiness of the tert-butyl substituent and also, possibly, tacticity effects. © 1990 Springer-Verlag.
