Abstract: An uncompounded particulate metallocene-produced polyethylene can have a multimodal molecular weight distribution and particle size distribution measured by obtaining at least four fractions by sieving. A set of Mw values including an Mw value for each fraction can be obtained. A set of Mn values including an Mn value for each fraction can be obtained. A ratio between a standard deviation value of the Mw set and a mean value of the Mw set can be equal to or less than 0.15. A ratio between a standard deviation value of the Mn set and a mean value of the Mn set can be equal to or less than 0.15. The uncompounded particulate metallocene-produced polyethylene can be prepared by a process that includes polymerization in an apparatus. The apparatus can include at least three serially connected loop reactors.

Abstract: A curable liquid rubber composition having improved viscosity stability is provided. The curable liquid rubber composition includes at least one functionalized crosslinkable polymer that is liquid at 25° C., contains at least one diene monomer in polymerized form, and is functionalized with one or more anhydride functional groups, one or more hydroxyl functional groups or one or more (meth)acrylate functional groups; at least one non-functionalized crosslinkable polymer that is liquid at 25° C., contains at least one diene monomer in polymerized form, and is not functionalized with anhydride, hydroxyl or (meth)acrylate functional groups; at least one metallic monomer coagent which is a metal carboxylate salt containing at least one (meth)acrylate functional group; and at least one inorganic filler. The curable liquid rubber composition has a total moisture content of not more than 1000 ppm, whereby controlling the amount of water reduces the tendency of the composition to exhibit an increase in viscosity over time.

Abstract: A composition is provided for making a polyurethane that may be incorporated in various products, such as a sealant, a coating, a caulk, an electric potting compound, a membrane, a sponge, a foam, an adhesives, and a propellant binder. The composition includes one or more polyols, one or more isocyanate-group containing compounds having an isocyanate group functionality of at least two, and optionally one or more chain extenders. At least one of the polyols is a farnesene-based polyol having a number average molecular weight less than or equal to 100,000 g/mol and a viscosity at 25° C. less than 10,000 cP. The farnesene-based polyol may be a homopolymer or a copolymer of farnesene. The composition may also comprise additional polyols, such as a polyol of a homopolymer or copolymer of a polydiene. Methods of preparing a polyurethane are also provided.

Abstract: Methods and systems for the dehydrogenation of hydrocarbons include a direct contact condenser to remove compounds from an offgas process stream. The reduction of compounds can decrease duty on the offgas compressor by removing steam and aromatics from the offgas. The dehydrogenation reaction system can be applicable for reactions such as the dehydrogenation of ethylbenzene to produce styrene, the dehydrogenation of isoamiline to produce isoprene, or the dehydrogenation of n-pentene to produce piperylene.
