Abstract: Gray expanded polystyrene achieving target molecular weight, bead size, bead distribution, and cell structure may be reproducibly prepared by suspension polymerization by introducing to the suspension polymerization an additive that is carbon black and/or graphite only after approximately 20 to 60 wt % of the styrene monomer has been converted to polystyrene. Introducing the additive at this point slows the polymerization rate, such as for an optimized period of time to allow for the droplet size to equilibrate to the desired target range. In one nonlimiting embodiment, the styrene polymerization rate has about 35 wt % to about 60 wt % styrene monomer remaining after about 3 hours from the beginning of polymerizing.

Abstract: When long chain primary alcohols are into expanded polystyrene (EPS) containing an additive such as carbon black or graphite to give gray EPS, the long chain primary alcohols act as color enhancing agents and generate a darker color as compared with an otherwise identical gray EPS absent the additive.

Abstract: Environmentally friendly demulsifiers are useful to break emulsions, e.g. water-in-oil and oil-in-water emulsions, particularly oilfield emulsions, where the demulsifiers are polymers made by reacting a suitable resin with at least two different monomers, one having a Hansen solubility parameter similar to ethylene oxide and the other having a Hansen solubility parameter similar to propylene oxide, and where the polymers have an absence of ethylene oxide and/or propylene oxide. In a non-limiting embodiment, suitable resins include butyl resin, nonyl resin, nonyl/butyl resin, amyl resin, nonyl/butyl/amyl resin, phenol/formaldehyde resin, and combinations thereof. Suitable monomers include caprolactone, lactic acid, lactide, methacrylic acid ester, stearyl ester, hexyl ester, lauryl ester, urethane, ethylene adipate, vinyl esters, amides, allyl ethers, vinyl ethers, vinyl chloride, vinyl acetate, acrylic acid methyl ester, and combinations thereof.

Abstract: A method for managing electronic content includes obtaining the content and associating top level contents of the obtained content with a deployment set. The top level content includes content that is specified by a user for deployment. The method also includes determining all dependencies of dependent content for each of the associated top level contents in the deployment set, incorporating the determined dependencies into discharge instructions for the deployment set, and generating a content deployment block including the associated top level contents, the dependent content, and the discharge instructions for the deployment set. The discharge instructions include dependency ordered deployment commands.

Abstract: Disclosed are polypropylene homopolymers, copolymers and mono and polyfunctional polypropylene derivatives as well as methods of preparing them. These polymers are prepared in the eresence of a metallocene catalyst and are isotactic. Applications using these polymers include but are not limited to, electrophotography toners, melt facture reduction agents, and compatibilizers.

Abstract: Polypropylene having high maleic anhydride content, between about 5 and about 45 g wt %, may be prepared by first reacting a metallocene-prepared polypropylene having terminal unsaturation with one mole equivalent of maleic anhydride to give polypropylene having a single unsaturation and a terminal succinic anhydride moiety. This product is then reacted with additional maleic anhydride in the presence of a free radical initiator (such as a peroxide or UV radiation) to give a polypropylene with maleic anhydride moieties along the backbone. The polypropylene product does not suffer scission or crosslinking with subsequently undesirable increases in molecular weight or viscosity. The maleic anhydride moieties provide reactivity to the polypropylene and thus expand its uses and applications.

Abstract: Disclosed are polypropylene derivatives and methods of preparing them. These derivatives can be used as, for example, compatibilizers. The degree of isotactic, syndiotactic or atactic structure of the compatibilizers can be modified based upon the character of the materials to be compatibilized to improve the effectiveness of the compatibilizer.

Abstract: Disclosed are wax based inks for phase change/hot melt inkjet printing or thermal transfer printing applications. Also disclosed are waxes useful for toners for use in electrostatographic printing applications. Both materials are prepared using a wax having a narrow melting range. The narrow melting range of the wax reduces energy requirements in printing applications. The use of the waxes also promotes release for high speed printing and especially promotes fast drying in wax based ink applications.

Abstract: Solid core particles encapsulated in a single coat of paraffin wax, the wax having a melting point of about 40.degree. to about 50.degree. C. and a solids content of from 100 to about 35% at 40.degree. C. and from 0 to about 15% at 50.degree. C. The paraffin coat may comprise 20 to 90% by weight of the particle and may be from 100 to 1,500 microns thick. The coat prolongs the time in which particles encapsulated therewith may remain active in aqueous environments.The encapsulated particle is made by spraying molten wax onto the particles in a fluidized bed. Liquid or powder cleaning compositions, particularly automatic dishwashing liquid detergents, may incorporate 0.01 to 20% by weight of the composition of the coated wax-encapsulated particles.
