摘要：

Partial specific volume (v2(-0)) of polybibenzoates with all-methylene and oxyethylene spacers have been determined in chloroalifatic solvents. The polybibenzoate with a heptamethylene spacer exhibits a more expanded state than the ones with one, two and three oxyethylene units in the spacer. A solvent effect on V2(-0) has been observed. Nevertheless, the values of V2(-0) in tetrachloroethane are in accord with the calculated by group contributions from rubbery polymers.
