Abstract
θcondition 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. θtemperatures 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 ℃. The Kθ values of PPSc were in the range of 29-34 × 10-4(dL/g) and calculated mean-square dimension ratios ((0 >/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.

Poly(ethylene terephthalate) (PET)와 에스테르기의 결합방향이 반대 형태인 poly(p-phenylene succinate) (PPSc)의 θ조건과 용해성은 PET보다 좋지 않았는데 phenol/1.1,2,2-tetrachloroethane(TCE) (6/4 w/w)와 phenol/TCE(4/6 w/w)은 PPSc의 양용매이었다. Dichloroacetic acid, m-cresol/TCE(5/5 w/w), phenol/1,2-dichloroethane(7/3 w/w), 그리고 phenol/m-cresol(5/5 w/w)에서 결정된 PPSc의 θ온도는 8.7-60 ℃의 범위에 있었으며 이들 θ온도에서 결정된 PPSc의 Kθ값은 29-33.5 x 10-4(dL/g)이었고 계산된 제곱평균 크기비(( /M)∞)는 1.10-1.22이었다. PET의 Kθ값이 22-25 x 10-4(dL/g)임을 고려할 때 PPSc가 PET보다 더 강직한 쇄임을 알았다.
