Urethane adhesive-laminated carpeting |
October 9, 2001 |
| Laminated carpeting consisting of a secondary backing adhered to a greige good of yarn tufted into a primary backing are prepared from polyurethane adhesives by single puddle processes which allow for lowered use of polyurethane while producing carpets exhibiting excellent delamination |

Polyurethane carpet backings with improved tuft bind |
January 9, 2001 |
| Improvements in tuft bind and/or elongation of tufted carpet may be achieved by selecting, as components of a tuft bind adhesive, one or more of: i) a polyol component comprising a low or ultra-low unsaturation polyoxypropylene polyol optionally containing up to 30 weight percent oxy |

Epoxide polymerization process |
February 22, 2000 |
| The amount of high molecular weight impurity present in a polyether polyol produced by alkoxylation of an active hydrogen-containing initiator using an epoxide such as propylene oxide and a substantially amorphous highly active double metal cyanide complex catalyst may be advantageously |

Stabilizer based on high molecular weight polyols having low monol content for polymer polyol pr |
January 11, 2000 |
| Stabilizer precursors and preformed stabilizers having induced unsaturation, and prepared from low intrinsic unsaturation-containing polyoxyalkylene polyether polyols may be used to form polymer polyols of higher solids content, lower viscosity, and superior filterability and particl |
