Short-Range Interaction Parameters of Poly(2-Methoxycyanurate) of Bisphenol-F
The poly(2-methoxycyanurate) of bisphenol-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 sigma, the effective segment length B(e), the characteristic ratio C(infinity), and the dihedral angle phi, were determined.
