Several kinds of linear copoly(hydroxyethers) (CPHEs) were prepared by the base-induced condensation of bisphenol with epichlorohydrin in a polar mixed solvent. The CPHEs were based on bisphenol AF [2,2-bis(4-hydroxypheny)hexafluoro-propane], and the composition ratio of bisphenol AF and bisphenol was 50 : 50 mol/mol. The CPHEs and the corresponding homopoly(hydroxyethers) (HPHEs) were characterized in terms of reduced viscosity, NMR, differential scanning calorimetry (DSC), solubility, and contact angle. NMR results indicated that the compositions of the copolymers were in good agreement with the feed compositions in the preparation. DSC analysis revealed that the CPHEs and HPHEs were amorphous polymers. The incorporation of bisphenol AF into the HPHE increased the solubility in many kinds of organic solvents when the CPHEs were compared with the corresponding HPHE. In the measurement of contact angles of water and plasma for poly(hydroxyethers) (PHEs) and common hydrophobic polymers, the peculiar phenomenon that the contact angles of plasma were higher than that of water was observed only in the case of PHEs.
