  • Patent number: 7838617
    Abstract: Commercial spandex can be prepared with greater efficiency, improved consistency and at lower costs from a high-solids content polyurethaneurea polymer solution. The polyurethaneurea is prepared using a combination of 4,4?-MDI and 2,4?-MDI, and an amount of chain extenders and chain terminators such that the polymer solution, prior to spinning, is highly soluble and has an appropriate pre-spun IV and primary amine content. Such spandex fibers, and the fabrics and garments comprising them, have good dyeability and colorfastness, as well as other desirable characteristics.

  • Patent number: 7834123
    Abstract: A two component polyurethane adhesive composition having one or more polyols as a first component and one or more isocyanates as a second component. The composition also comprises one or more catalysts and one or more blocking agents to delay the curing reaction. The composition provides long open time, improved wet out of the substrates to be bonded, a rapid cure rate and excellent final bond performance at room and elevated temperatures. Optional ingredients, such as fillers, chain extenders and plasticizers may be added as desired. In one embodiment, the catalyst is a tin catalyst such as dibutyl tin dilaurate which may optionally be combined with other catalysts such as tertiary amines. The blocking agent in one embodiment is 8-hydroxyquinoline.
