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: Disclosed is a composition of a functionalized polyalphaolefin comprising the reaction product of admixing (a) an alpha-olefin monomer having at least 10 carbon atoms; (b) an unsaturated functionalizing compound; and (c) a polymerization initializer, under reaction conditions sufficient to polymerize the alpha-olefin monomer and unsaturated functionalizing compound. Free radical initiators, especially peroxides are disclosed to be useful in preparing the functionalized polyalphaolefin. The functionalized polyalphaolefins are disclosed to be useful in preparing inks, toners, coatings, candle waxes, lubricating oils, and personal care products.

Abstract: Polypropylene having high maleic anhydride content, between about 5 and about 45 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: Coupled alcohol ethoxylates made by reacting alcohol ethoxylates with a diisocyanate have been found to improve the thermal properties of toner compositions and powder coatings. The alcohol ethoxylates have saturated linear alcohol portions of from about 20-70 carbon atom chain lengths. The diisocyanates may be aromatic diisocyanates such as toluene diisocyanate (TDI) and/or methylenediphenyl diisocyanate (MDI). Preferably, about one mole of diisocyanate is reacted with about two moles of the alcohol ethoxylates to form the coupled alcohol ethoxylates that are useful compatibilizers to improve the homogeneity of toner compositions and powder coating compositions.
