Abstract: An apparatus and method for determining the coefficient of friction for plastic articles utilizes a stationary sample and a rotatable sample in contact with the stationary sample. The apparatus and method are particularly useful in measuring the coefficient of friction for articles having non-planar surfaces and particularly plastic articles having irregular and arcuate surfaces, such as thermoplastic bottles or preforms. The apparatus (10) includes: a frame (12), a vertical member (16) attached to the frame, a rod member (18) affixed to the vertical member (16), a torque generating source (14), a device (28) for sensing the torque generated, and a computer (22) for recording the torque measurements and for calculating the coefficient of friction. The apparatus also includes screw caps (33) appropriately positioned for holding the two samples to be tested and a weight (20) for applying a downward force to the stationary sample while applying torque to the rotatable sample. The torque applied is computer controlled and at the moment of slip is detected. From the torque measurements, the computer calculates the coefficient of friction between the two sample materials.

Abstract: A solid concentrate is provided having a combination of a transition metal present in an amount ranging from 1000 to 40,000 ppm (weight by metal) and a polyester polymer present in an amount of at least 40 wt.% based on the weight of the concentrate. Concentrates made with highly modified polyester polymers are easy to compound with transition metals forming less brittle polymer upon melt extrusion. Bottle preforms and oxygen scavenging bottles can be made from these concentrates by combining solid polyester particles, solid polyamide particles, and solid these concentrate particles c into an melt processing zone, forming a melt, and forming an article directly from the melt. The b* color and the L* color and the haze levels of the preforms are improved over the preforms made with liquid carriers instead of solid concentrates. The particles are also advantageously simultaneously dried in a drying zone under conditions effective to at least partially remove moisture from the blend to thereby further improve the b* color and L* color.

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