Valence Angle Chains with Hindered Rotation

Figure 4-18. Variation of the characteristic ratio Cv with the number N of bonds in the chain molecule. (I) Segment chain (II) valence angle chain with free rotation (III) valence angle chain with hindered rotation and three rotational isomers of equal energy (IV) valence angle chain with hindered rotation and a conformational energy of Eg Et= 2.09 kJ / mol and (V) valence angle chain with hindered rotation and neighboring group influence and A (j+ — AEg = 8.30 kJ/mol. Valence angle =112° (after P. J. Flory). Figure 4-18. Variation of the characteristic ratio Cv with the number N of bonds in the chain molecule.

Equation (A4-21) allows the theoretically important end-to-end chain distance to be calculated from the experimentally accessible (e.g., by light scattering measurements) radius of gyration. This calculation remains valid for the linear valence angle chain and the linear valence angle chain with hindered rotation, but is not valid for polymers in good solvents. [Pg.147]
