Physical-Chemical Properties of Articulated Rodlike Polymers

Abstract

The properties of PBT, articulated copolymers of PBT (SPBT), and PBO (SPBO), and copolymers of PBT and PBO in dilute solutions are discussed. Light scattering methods are used to determine the molecular weight, the second virial coefficient, the root-mean-square radius of gyration, and a hydrodynamic radius. Photon correlation scattering is used to determine the other parameters. The anisotropic light scattering is used to determine an optical molecular anisotropy which provides information on the rodlike nature of the chain.
