Formal expressions are derived for the mean square dipole moment (MSM) and the mean square end-to-end (MSD) distance of polar, monosubstituted vinylic polymers. Without introducing a particular model, these expressions are written in a form which emphasizes any analogy between MSM and MSD. Three different types of characteristic coordinate systems are attached to the polymer chain instead of the usual one proposed previously by Eyring. It is shown that for the most general case no correlation will exist between MSM and MSD. For polymers with a single atom or a rigid molecular group as the polar side-chain, different possibilities for isotactic and syndiotactic structures are discussed regarding any such correlation. (This discussion may be extended to polymers where the motion of the side group is independent of the configuration of the polymer as a whole.) Further, conclusions formulated previously for MSM and concerning the cancellation of effects due to long range interactions, are shown to be valid for very particular polymers of syndiotactic structure only. |
