Notes:
Mean-square dipole moments 〈μ2〉0 for the (atactic) poly(4-methyl-1,3-dioxolane) chain [CH2OCH(CH3)CH2O—] were determined from dielectric-constant measurements carried out on two fractions dissolved in benzene. Simple examination of the chain structure leads to the predictions that this polymer should have a significantly larger value of 〈μ2〉0 than poly(1,3-dioxolane) itself, but that 〈μ2〉0 should be nearly independent of stereochemical structure. The first expectation is confirmed by the experimental results obtained, and the second by calculated results based on rotational isomeric state theory.
