    摘要： A bulk of polyester polymer particles comprising polyester polymer comprising greater than 75% virgin polyester polymer, the particles having: A) an It.V. of at least 0.72 dl/g, and B) 10 ppm or less of residual acetaldehyde; and C) at least two melting peaks, wherein one of said at least two melting peaks is a low peak melting point within a range of 140° C. to 220° C. and having a melting endotherm area of at least the absolute value of 1 J/g. The particles may also have a degree of crystallinity within a range of 20% and a maximum degree of crystallinity Tcmax defined by the equation: Tcmax=50%−CA−OH where CA is the total mole % of all carboxylic acid residues other than terephthalic acid residues, based on 100 mole % of carboxylic acid residues, and OH is the total mole % of all hydroxyl functional compound residues other than ethylene glycol residues, based on 100 mole % of hydroxyl functional compounds residues. The preforms and bottles made from these particles can be obtained by melt processing these particles at either lower overall power, faster screw speeds, lower residence time, or lower overall cycle time to thereby reduce the level of residual acetaldehyde generated in the melt.

    摘要： 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. The polyester polymer composition can be made to high IV from the melt phase while avoiding solid state polymerization.

    摘要： Polymer blends are disclosed that comprise one or more polybutadiene homopolymers or copolymers having at least one functionality capable of entering into condensation reactions; one or more polyethylene terephthalate homopolymers or copolymers obtained using a catalyst system comprising aluminum atoms and one or more alkaline earth metal atoms, alkali metal atoms, or alkali compound residues, optionally obtained by a melt-phase polymerization process; and one or more transition metal atoms. The blends are useful for packaging, and exhibit improved oxygen-scavenging activity compared with blends made using many conventional polyethylene terephthalate polymers prepared with conventional catalyst systems.
