Abstract: A thermoplastic composition comprising from about 50 to about 99 by weight percent of a nylon 6,6 resin, from about 1 to about 50 by weight percent of a polymer performance modifier and about from 0.01 to about 25 by weight percent of a silicone based additive, wherein the silicone based additive comprises an ultrahigh molecular weight siloxane polymer that is unfunctionalized and non-reactive with the polyamide resin, wherein the thermoplastic composition has an impact strength value which is greater than the combination of the polyamide resin and the polymer performance modifier or the combination of the polyamide resin and the silicone based additive and wherein the thermoplastic composition has an ultimate tensile strength that is at least 80% that of the combination of the polyamide resin and the polymer performance modifier.

Abstract: The present invention relates to a process for hydrocyanating 3-pentenenitrile. The process can include feeding 3-pentenenitrile and HCN to a hydrocyanation reaction zone that includes a Lewis acid promoter, nickel, and a phosphorus-containing ligand. In various embodiments, the process can also include controlling water concentration within the hydrocyanation reaction zone sufficient to maintain a high activity of the ligand catalyst complex while recycling at least a portion of the ligand catalyst complex.

Abstract: Disclosed is a process for the separation of water from a liquid phase medium containing an aliphatic carboxylic acid using azeotropic distillation in the presence of an entrainer. The entrainer, water, and organics are subsequently separated, wherein the entrainer is recycled back to the azeotropic distillation column and organics recycled back to the oxidation reactor.

Abstract: This document describes biochemical pathways for producing adipic acid, caprolactam, 6-aminohexanoic acid, hexamethylenediamine or 1,6-hexanediol by forming two terminal functional groups, comprised of carboxyl, amine or hydroxyl groups, in a C6 aliphatic backbone substrate. These pathways, metabolic engineering and cultivation strategies described herein rely on CoA-dependent elongation enzymes or analogues enzymes associated with the carbon storage pathways from polyhydroxyalkanoate accumulating bacteria.

Abstract: This disclosure relates to strategies for in vivo production of certain carbon-based products, for example, aminated aliphatic compounds having a carbon chain length of C5-C19. Specifically, 7-aminoheptanoic acid is produced using a transaminase from Chromobacterium violaceum from pimelate semialdehyde using alanine, GABA (gamma aminobutyric acid) or 6-ACA as amino donors.

Abstract: Disclosed herein are methods, compositions, and hosts for synthesizing hydrocarbons, and derivatives thereof, comprising one or more isoprene units as well as salts or derivatives thereof. An aspect of the present invention thus relates to a method for biosynthesizing hydrocarbons in a recombinant host selected from non-pathogenic members of the genera Ralstonia, Wausteria, Cupriavidus, Alcaligenes, Burkholderia, or Pandoraea. Said recombinant host comprises an exogenous nucleic acid sequence encoding a polypeptide having an enzyme activity selected from 1-deoxy-D-xylulose-5-phosphate synthase (DXS) activity (EC 2.2.1.7) and isoprene synthase enzyme activity (EC 4.2.3.27).
