Abstract

Abstract The authors have investigated the hydrodynamic (sedimentation, diffusion, viscometry) and optical (birefringence) properties of solutions of para-aromatic copolyesters obtained by polycondensation of three components-terephthaloyl chloride, 4,4′-dihydroxy-1,1-dinaphthoyl and 2,2-propane diol—for different molar ratios. A quantitative molar evaluation of the parameter of equilibrium rigidity of the copolymers - the length of the statistical Kuhn segment — is made.
