Abstract: A method of manufacturing an article comprises rotomolding at least one polymer comprising a poly(aryl ketone), such as PEKK, under conditions effective to produce a rotomolded article having an impact value of at least 35 in-lbs. A rotomolding method comprises heating the mold for a period of time after the internal air temperature of the mold reaches the highest melting point of the at least one polymer. Methods also include using a PEKK powder with a bulk density of at least about 400 g/L. Rotomolded articles of the present invention have impact values of between about 40 in-lbs to about 95 in-lbs, and in particular embodiments greater than about 95 in-lbs.

Abstract: Aspects of the present invention relate to systems and processes for obtaining desired mercaptans or thiophenes from a feed stream containing a mixture of mercaptans, thiophenes and other components. In one aspect of the invention, a system for separating one or more components from a feed stream of mixed mercaptans includes one or more distillation columns in connection with a feed containing mercaptans, the distillation column having a rectification section, a stripping section, and a feed side section separated from a side draw section by a dividing wall that extends from the rectification section to the stripping section. The distillation column further being in connection with a condenser and a reboiler; and a distillate stream, a side drawn stream, and a bottoms stream.

Abstract: The present invention relates to blowing agent compositions comprising at least one hydrofluoroolefin (HFO) selected from cis- and/or trans- 1,3,3,3-tetrafluoropropene (HFO-1234ze) and at least one hydrochlorofluoroolefin (HCFO) selected from cis- and/or trans- 1-chloro-3,3,3-trifluoropropene (HCFO-1233zd) used in the preparation of foamable thermoplastic compositions. The blowing agent compositions are useful in the production of low density insulating foams with improved k-factor.

Abstract: Aspects of the invention relate to systems and processes for recovering methanesulfonic acid, in a purified form, from a composition additionally including sulfur trioxide. In accordance with one aspect, the invention provides a process that includes separating a feed stream comprised of hydrocarbons, methanesulfonic acid, sulfur trioxide, and optionally sulfuric acid to produce a light stream comprised of hydrocarbons and a heavy stream comprised of methanesulfonic acid and sulfur trioxide; contacting (e.g., by mixing) the heavy stream with a reactive additive capable of reacting with sulfur trioxide, under conditions effective to cause reaction of the reactive additive with the sulfur trioxide to produce a heavy reaction product having a boiling point higher than the boiling point of methanesulfonic acid; and separating the heavy stream using a distillation column to produce a distillate stream consisting essentially of methanesulfonic acid and a bottoms stream comprising the heavy reaction product.

Abstract: A method of making an ester comprised of at least one cyclohexene oxide moiety is provided, involving the steps of a) esterifying an alcohol with a carboxylic acid-substituted cyclohexene to obtain an intermediate comprised of at least one carboxylate-substituted cyclohexene moiety; and b) epoxidizing the intermediate obtained in step a) with an epoxidizing agent to obtain the ester comprised of at least one cyclohexene oxide moiety. The esters have utility as acid scavengers, plasticizers and reactive resins.

Abstract: The invention relates to sized reinforcing fibers that comprise a reinforcing fiber sized with a fluoropolymer. The fluoropolymer is functionalized and/or the reinforcing fiber is sized with a compatible functional non-fluorinated polymer that is compatible with the fluoropolymer. Functionalization of the fluoropolymer or the compatible non-fluorinated polymer provides enhanced properties, such as increased adhesion to the reinforcing fiber.

Abstract: The invention relates to a solid porous article containing sub-micron functional additive particles held together using discrete sub-micron polymer binder particles. The porous article preferably also contains a majority of primary active particles in the 1 to 300 micron range. The solid porous articles are used to separate, precipitate, and/or trap components of a fluid that passes through the porous article. The solid porous articles are used to separate and trap components of a fluid that passes through the porous article. Preferred binders are polyvinylidene fluoride resins, such as Kyblock® resins from Arkema Inc.

Abstract: Methods of synthesizing fluorosilanes containing cyano-substituted alkyl groups are provided. For example, 3-cyanopropyldimethylfluorosilane may be produced by reacting tetramethyldisiloxane and boron trifluoride to obtain fluorodimethylsilane and then reacting the fluorodimethylsilane with allyl cyanide, in the presence of a hydrosilylation catalyst.

Abstract: Novel fluorosilicon nitrile compounds, and methods of preparing them, are described. The fluorosilicon nitrile compounds are characterized by having a total of four substituents attached to a silicon atom, wherein one or two of the substituents are fluorine atoms, one or two of the substituents are cyanoalkyl groups, which are the same as or different from each other, and the remainder of the substituents, if any, are alkyl groups, which are the same as or different from each other.
