  • Patent number: 8791187
    Abstract: A polyester composition containing: a) aluminum atoms; and b) alkaline earth atoms or alkali metal atoms or alkali compound residues such as lithium atoms; and c) particles comprising titanium, zirconium, vanadium, niobium, hafnium, tantalum, chromium, tungsten, molybdenum, iron, or nickel atoms or combinations thereof, where the particles improve the reheat rate of the polyester composition. The polyester polymer compositions may also contain phosphorus catalyst deactivators/stabilizers. The polyester compositions and the articles made from the compositions such as bottle preforms and stretch blow molded bottles have improved reheat rate while maintaining low haze, high L*, a b* below 3, and have low levels of acetaldehyde. In the process for making the polyester polymer, the polymer melt is polycondensed in the presence of a) and b), with the particles c) added in a melt phase process or added to the polymer in an injection molding machine or extruder.

  • Patent number: 6458915
    Abstract: In a process for producing a reactor grade polyester, a poly(1,4-cyclohexylenedimethylene 1,4-cyclohexanedicarboxylate) has a reduced amount of isomerization of the trans-isomer to the cis-isomer of 1,4-dimethylcyclohexanedicarboxylate and an increased polymerization rate by the addition of a phosphorus-containing compound to the reaction process. In step (a) of the process, a diacid comprising at least 80 mole percent 1,4-cyclohexanedicarboxylic acid or an ester derivative of the diacid comprising at least 80 mole percent 1,4-dimethylcyclohexanedicarboxylate is reacted with a glycol comprising at least 80 mole percent 1,4-cyclohexanedimethanol at a temperature sufficient to effect esterification for the diacid or transesterification for the ester derivative. In step (b), the product of step (a) is subjected to temperatures and pressures in the presence of a suitable catalyst to effect polycondensation.

  • Patent number: 6429278
    Abstract: In a process for producing a polyester containing 1,4-cyclohexanedimethanol (CHDM) as one of its glycol components, an aqueous or a methanolic slurry comprising CHDM and a dicarboxylic acid is prepared. The slurry is maintained at a temperature below the melting point of CHDM. The slurry is then fed into a reactor. The slurry is esterified at sufficient temperatures and pressures, and optionally in the presence of a suitable catalyst, to effect esterification. A prepolymer is formed. The prepolymer is then polycondensed at sufficient temperatures and pressures in the presence of a suitable catalyst to effect polycondensation to form a polyester.
