  • Polyethylene glycol modified polyester fibers and method for making the same
    Publication number: 20030134117
    Abstract: Disclosed is a method of copolymerizing polyethylene glycol (PEG) and branching agent into polyethylene terephthalate (PET) to achieve a polyethylene glycol-modified polyester composition that can be spun into filaments. Fabrics made from fibers formed from the copolyester composition possess wicking, dyeability, and tactility properties that are superior to those of fabrics formed from conventional polyethylene terephthalate fibers of the same yarn and fabric construction. Also disclosed are polyethylene glycol modified copolyester compositions, fibers, yarns, and fabrics.

  • Methods of post-polymerization extruder injection in condensation polymer production
    Patent number: 6590069
    Abstract: The invention is a novel method for the late introduction of additives into condensation polymers. The method employs a reactive carrier that functions as a delivery vehicle for one or more additives. The reactive carrier reacts with the condensation polymers, thereby binding the reactive carrier in the polymer resin and preventing the emergence of the reactive carrier from the polymer resin during subsequent thermal processing.

  • Methods of post-polymerization injection in condensation polymer production
    Patent number: 6573359
    Abstract: The invention is a novel method for the late introduction of additives into a process for making condensation polymers. The method employs a reactive carrier that functions as a delivery vehicle for one or more additives. The reactive carrier reacts with the condensation polymers, thereby binding the reactive carrier in the polymer resin and preventing the emergence of the reactive carrier from the polymer resin during subsequent thermal processing.

  • Polyethylene glycol modified polyester fibers
    Patent number: 6509091
    Abstract: Disclosed is a polyethylene glycol modified copolyester fiber that has exceptional moisture management characteristics and that can be formed into exceptionally comfortable fabrics. The copolyester fiber includes polyethylene terephthalate in an amount sufficient for the copolyester fiber to possess dimensional stability properties substantially similar to those of conventional, unmodified polyethylene terephthalate fibers, polyethylene glycol in an amount sufficient for the copolyester fiber to possess wicking properties that are superior to those of conventional, unmodified polyethylene terephthalate fibers, and chain branching agent in an amount less than about 0.0014 mole-equivalent branches per mole of standardized polymer.

  • Polyester bottle resins having reduced frictional properties and methods for making the same
    Patent number: 6500890
    Abstract: The invention is a polyester resin that includes between about 20 and 200 ppm of an inert particulate additive, preferably selected from the group consisting of surface-modified talc and surface-modified calcium carbonate. The invention is also a method of making the polyester resin, which is capable of being formed into low-haze, high-clarity bottles possessing reduced coefficient of friction.
