The poly(2-methoxycyanurate) of bisphenoi-F (PMCBF), is known for its thermal stability. PMCBF was separated into its various fractions by using a fractional precipitation method, and these fractions were then characterized by viscometry and light scattering methods. The unperturbed dimensions of the polymer chain were computed by using various two-parameter theories and compared with those obtained from calculations based on a freely rotating model. To characterize the flexibility of the polymer, various parameters, such as the stiffness parameter tr, the effective segment length Be, the characteristic ratio C~, and the dihedral angle ~, were determined.
