  • Polyester polymerization catalyst, polyester produced by using the same, and process for producing polyester
    Patent number: 7144614
    Abstract: This invention provides a novel polymerization catalyst other than antimony compounds, polyester produced by using the same and a process for producing polyester. The polycondensation catalyst of this invention is a polyester polymerization catalyst comprising an aluminum compound and a phosphorus compound having a specific structure. Further, this invention relates to polyester produced by using this polyester polymerization catalyst and a process for producing polyester. Further, this invention relates to fibers, films and hollow molded articles comprising the polyester.

  • Polymerization catalyst for polyester, polyester produced with the same, and process for producing polyester
    Patent number: 7132383
    Abstract: A polymerization catalyst for polyester production which contains neither a germanium compound nor an antimony compound as a major component. It contains aluminum as the main metallic ingredient, has excellent catalytic activity, and gives a polyester which is effectively inhibited from suffering thermal degradation, during melt molding, without deactivating or removing the catalyst, and is excellent in thermal stability, stability to thermal oxidation, and hydrolytic resistance. The polymerization catalyst contains as a first metallic ingredient at least one member selected among aluminum and compounds thereof and further contains a phosphorus compound represented by a specific chemical formula. The polyester produced with this catalyst is usable as fibers, films, sheets, various moldings including hollow moldings, etc.
