    Abstract: In the hydrocyanation reaction of butadiene proceeding through pentenenitriles to adiponitrile, catalysis by complexes of zerovalent nickel with bidentate phosphorus-based ligands of the NiL 2 A type wherein L 2 is a bidentate ligand and A is an unsaturated compound, can be rate-limited by the solubility of the catalytic complex. The present invention concerns solvent compositions for the nickel-ligand complex comprising mixtures of unsaturated nitriles that provide for increased metal solubility, particularly in the absence of a Lewis acid promoter, resulting in higher hydrocyanation reaction rates in an industrial-scale process for production of important nylon manufacturing intermediates. The mixed nitrile solvent compositions can include mixtures of pentenenitriles and/or methylbutenenitriles. The mixtures of mixed unsaturated nitriles can be, at least in part, from recycle streams from the hydrocyanation reaction for which the nickel-bidentate ligand complexes are used as catalysts.

    Abstract: The disclosures herein relate to a process for making polyamides from stoichiometrically imbalanced mixtures. This process includes the production and subsequent use of solidified stoichiometrically imbalanced components comprising mixtures of diacids and diamines. This stoichiometric imbalance is defined by a component molar ratio equal to moles of dicarboxylic acid units divided by moles of diamine units; and wherein this molar ratio is different from unity. This process com¬ prises steps of: a) forming an acid-rich solidified first component in a dry or moisture containing state by; b) contacting at least a dicar¬ boxylic acid with at least a diamine in a molar ratio of greater than 1:1; c) forming an amine-rich solidified second component in a dry or moisture containing state by; d) contacting at least a dicarboxylic acid with at least a diamine in a molar ratio of less than 1:1; e) contacting the acid-rich first component with the amine-rich second component in a molten state or a solution state and f) forming a first composition having a composition molar ratio g) such that a total dicarboxylic acid content and a total diamine content, supplied by said first and second components, is from about 0.95 to about 1.05; h) heating the first composition with agitation in the molten state and under pressure to a sufficiently high temperature for a polyamidation reaction to and subsequently, i) forming a second composition comprising a polyamide.

    Abstract: The present invention relates to moldable composite articles, and particularly to a molded nonwoven fibrous article, and specifically to an automobile headliner that has improved physical properties at low weight. There is a need to minimize the weight of the headliner and the critical parameter is minimum sag. For a molded non-needlepunched batt in the weight range of 1000 to 1200 grams per square meter (gsm), the sag at 91°C must be less than 10 mm, when cantilevering a distance of 28cm. The stiffness, strength and toughness of the batt should be greater than 2 N/mm, 17N and 70% respectively. In the first embodiment, the thermoplastic binder is a bicomponent fiber with an adhesion promoted polyolefin sheath and a polyester core. In the second embodiment, the matrix fiber is a synthetic fiber with a modulus greater than 10 cN/tex. In the third embodiment the matrix fiber is a natural fiber. In the fourth embodiment the bicomponent fiber contains a filler such as carbon black or titanium dioxide.
