    • PURPOSE: To obtain a high-MW polyester, by reacting starting materials for polycondensation in the presence of both a specified direct-polycondensation reagent and an electron-donating high-MW polymer as a matrix.
      CONSTITUTION: A direct-polycondensation reagent is used which contains (i) a triphenylphosphine compound (e.g., triphenylphosphine), (ii) a compound having polyhalogenated carbon atoms in the molecule, e.g., hexachloroethane, and (iii) a pyridine, e.g., β-picoline. Namely, a diol (e.g., catechol) and a dicarboxylic acid (e.g., phthalic acid) or a hydroxycarboxylic acid (e.g., m-hydroxybenzoic acid) are subjected to direct polycondensation in the presence of both an electron-donating high-MW polymer capable of forming hydrogen bonds with the polycondensation materials (e.g., polyvinylpyridine, solution viscosity ≥about 0.5) as a matrix and the above reagent.

    • Condensation polymers of high molecular weight, such as polyesters, polyureas, and polyamides, are usually prepared at temperatures of 200.degree. C. or greater. However, by utilizing the catalyst systems of the present invention, condensation polymers can be synthesized at much lower temperatures. The polycondensation catalyst systems of the present invention are particularly useful for synthesizing aliphatic polyesters, such as polyethylene terephthalate, from dicarboxylic acids and aliphatic glycols. The present invention more specifically discloses a process for the synthesis of an aliphatic polyester comprising polymerizing at least one dicarboxylic acid with at least one aliphatic glycol in the presence of (1) at least one phosphorus containing compound which contains at least one trivalent or pentavalent phosphorus atom which is bonded directly to at least one phenyl group, (2) an acid acceptor, and (3) at least one halogenated organic compound. It is preferred to utilize a polymeric agent having bound acid acceptor groups as the acid acceptor in the process of the present invention.
    • 高分子量的缩合聚合物,如聚酯,聚脲和聚酰胺,通常在200℃或更高的温度下制备。 然而,通过利用本发明的催化剂体系,可以在更低的温度下合成缩聚物。 本发明的缩聚催化剂体系特别适用于从二羧酸和脂肪族二醇合成脂肪族聚酯,如聚对苯二甲酸乙二醇酯。 本发明更具体地公开了一种用于合成脂族聚酯的方法,其包括在(1)至少一种含磷化合物存在下使至少一种二羧酸与至少一种脂肪族二醇反应,所述至少一种含磷化合物含有至少一种三价或五价磷 直接与至少一个苯基键合的原子,(2)酸受体和(3)至少一种卤化有机化合物。 在本发明的方法中优选使用具有结合的酸受体基团的聚合物作为酸受体。
