Abstract: Disclosed herein are processes for preparing an ?,?-Cn-diol, wherein n is 5 or greater, from a feedstock comprising a Cn oxygenate. In some embodiments, the process comprises contacting the feedstock with hydrogen gas in the presence of a catalyst comprising metals M1, M2, and M3 and optionally a support, wherein: M1 is Mn, Cr, V, or Ti; M2 is Ni, Co, or Fe; and M3 is Cu, Ag, Pt, Pd or Au; or M1 is Pt or Rh; M2 is Cu, Ni or Pd; and M3 is Mo, Re or W. The Cn oxygenate may be obtained from a biorenewable resource.

Abstract: Disclosed is a molded or extruded thermoplastic article, including a thermoplastic polyamide composition including (a) a polyamide resin; (b) one or more polyhydroxy polymer(s); (c) one or more co-stabilizer(s); (d) one or more reinforcement agents; (e) and, optionally, a polymeric toughener.
Abstract: This invention relates to the synthesis and isolation of colloidal silver particles through the use of thermomorphic polymers and the resulting composition. It further relates to the use of the resulting composition in the preparation of inks for printing with silver-containing inks.
Abstract: The present invention is generally directed to perfluoroalkylated fluorene polymers. It further relates to a process for preparing the polymers and devices that are made with the polymers.
Abstract: The invention relates to a method for the dehalogenation of organohalogen compounds commonly found as pollutants in soil and ground water. The instant method utilizes anaerobic bacteria comprising an extracellular electron transfer protein coupled with a tetrapyrrole catalyst to effect the reductive dehalogenation of halogenated organics. Optionally, an electron transport mediator may be used to enhance the rate of dehalogenation.
Abstract: An injection moldable, electrostatically paintable polyolefin composition comprising 100 parts of an ethylene/higher .alpha.-olefin copolymer rubber, 20-100 parts of a crystalline propylene polymer, and carbon black, said carbon black having a mean particle diameter of from about 15-30 millimicrons, an oil absorption number (A) having a minimum value of about 40 cc/100 g. and a maximum value wherein A is calculated from the formula A = 0.3116D.sup.2 -18.708D +359.67, wherein D is the mean particle diameter, with the proviso that the maximum value of A is never greater than 130 cc/100 g., said carbon black present within a range determined by the following formulas:Minimum parts carbon black = 2.157D -0.0145D.sup.2 -0.00467AD -5.03;maximum parts carbon black = 0.863D -0.005OD.sup.2 -0.00625AD -0.3663A +0.00159A.sup.2 +49.19;wherein A and D have the values given hereinabove and parts carbon black is based upon the total weight of polymers.
