摘要：

Direct polycondensation of p-aminobenzoic acid (ABA) or p-hydroxybenzoic acid (HBA) was carried out in solutions of polyarylate (copolyester from tere-/iso-phthalic acids (50/50)and bisphenol A) at 25°C in the presence of triphenylphosphine and hexachloroethane as an initiator for the direct polycondensation of these monomers. Solution casting after the direct polycondensation provided opaque films in which aromaticpolyamide or polyester was finely dispersed within the matrixof polyarylate. Mechanical properties of these films indicatedincrease in modulus and tensile strength at elevated temperatures.In-situ direct polycondensation leads to the formation of newmolecular composite materials. © 1990, The Society of Polymer Science, Japan.
