Abstract
θ condition and unperturbed dimension of poly(p-phenylene succinate) (PPSc) having the inversed ester group with respect to poly(ethylene terephthalate) (PET) were evaluated from the intrinsic viscosity measurement. PPSc had a lower solubility than PET and phenol/1,1,2,2-tetrachloroethane (TCE) (6/4 w/w) and phenol/TCE (4/6 w/w) were good solvents for PPSc. θ temperatures determined from polymer solutions in dichloroacetic acid, m-cresol/TCE(5/5 w/w), phenol/ 1,2-dichloroethane (7/3 w/w), and phenol/m-cresol (5/5 w/w) were in the range of 9-60°C. The Kθ values of PPSc were in the range of 29-34 × 10-4 (dL/g) and calculated mean-square dimension ratios ((<ro2>/M)∞) were in the range of 1.10-1.22 under θ condition. Considering that the Kθ values of PET reported are in the range of 22-25 × 10-4 (dL/g), PPSc has a more rigid chain conformation than PET.
