This book was released on 1979 with total page 63 pages. Available in PDF, EPUB and Kindle. Book excerpt: An experimental study is reported of the quiescent and flow birefringent characteristics of two liquid crystalline polymer solution systems, poly-p-phenylene terephthalamide (PPD-T) in sulfuric acid and hydroxypropyl cellulose (HPC) in water over a range of concentrations. It is shown that, for the quiescent state, the dilute solutions are optically isotropic while the concentrated solutions consist of negatively birefringent domains. During flow at low deformation rates, moving domains are still seen. At higher deformation rates a homogenous highly birefringent fluid is obtained. The birefringence increases with concentration at constant deformation rate and exhibits a major increase as the liquid crystalline state is formed. The source of the birefringence is due to: (1) anisotropy of polarizability of oriented macromolecules, and (2) difference in refractive index of solvent and oriented macromolecules (form birefringence). The results are interpreted in terms of the level of polymer orientation which may be developed in flow for liquid crystalline polymer solutions as compared to solutions of flexible macromolecules.

This book was released on 1978 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: The dilute solution viscometric behavior of poly(m-phenylene isophthalamide) dissolved in LiCl/dimethylacetamide was studied. Important aspects of this investigation included interactions between dimethylacetamide and LiCl, polymer-polymer association, and the capability of poly(m-phenylene isophthalamide) to become a polyion when dissolved in LiCl/Dimethylacetamide. Counterion interaction with the polyion and the ability to control the ion concentration gave rise to interesting variations in the hydrodynamic volume of poly(m-phenylene isophthalamide) leading to a maximum in its intrinsic viscosity as a function of LiCl concentration.
