Polymers of substituted cyclopentenes |
December 30, 2003 |
| Substituted cyclopentenes, such as alkyl cyclopentenes, are polymerized by selected .alpha.-imine complexes of nickel and palladium. The polymers are useful as molding resins or elastomers. Also disclosed herein are novel catalysts for the polymerization of cyclopentenes to form novel hi |

Polymerization process |
February 18, 2003 |
| Processes for the polymerization of olefins in which late transition metal complexes, such as nickel, iron, cobalt and palladium complexes, are used as a polymerization catalyst have improved polymer productivity when oxidizing agents are present during at least a portion of the poly |

Polymerization of olefins |
October 23, 2001 |
| Certain alkylhaloaluminoxanes and other alkylhaloaluminum compounds, when used as cocatalysts for the polymerization of olefins with complexes of transition metals and neutral bidentate ligands give good yields of polyolefin when using less of the alkylhaloaluminoxane than other types of |

Process for modifying aliphatic polyamides with polyurea |
November 2, 1999 |
| The end groups of an aliphatic polyamide may be changed by reacting a polyurea with a molten aliphatic polyamide at temperatures of about 260.degree. C. or more. Carboxyl end groups are controllably converted to amine end groups. This is especially useful for controlling the dyeability |

Melt-processible aromatic polyamide from N,N'-isophthaloyl bis lactam |
August 4, 1992 |
| Melt-processible aromatic polyamides are obtained by reacting certain N,N'-isophthaloyl bis(lactam) compounds with certain aromatic diamines. |
