Abstract: A process for producing a nanocomposite of a halogenated elastomer and an inorganic, exfoliated clay includes the in-situ protonation of a modifier, which may be an alkylamine, arylamine or an alkylarylamine. This process can be integrated with a polymer halogenation process. The nanocomposite so formed has improved air barrier properties and is suitable for use as a tire innerliner or innertube.

Abstract: Copolymer are formed by polymerizing C4 to C7 isoolefin monomers and alkyl-styrene monomers. The method comprises first providing feed streams into a reactor. The various feed streams provide monomers, a polar diluent or polar diluent mixture, and a catalyst system into the reactor. In the reactor, the feed streams contact one another so that the monomers form a polymer in a stable slurry, wherein the amount of polymer in the slurry yields a slurry concentration greater than 22 wt %. The ratio of moles of polymer formed per mole initiator is in the range of 0.25 to 4.0 moles polymer per mole of initiator.
Abstract translation: 共聚物通过聚合C4至C7异烯烃单体和烷基苯乙烯单体形成。 该方法包括首先向反应器提供进料流。 各种进料流将单体，极性稀释剂或极性稀释剂混合物和催化剂体系提供到反应器中。 在反应器中，进料流彼此接触，使得单体以稳定的浆料形成聚合物，其中浆料中的聚合物的量产生大于22重量％的浆料浓度。 每摩尔引发剂形成的聚合物的摩尔比在每摩尔引发剂为0.25-4.0摩尔聚合物的范围内。

Abstract: The invention pertains to improved lubricating oil dispersants wherein a fractionating polymer is prepared prior to functionalization (e.g., in the Koch reaction) for making dispersant additives. In one aspect, it was discovered that by fractionating a polymer to remove light hydrocarbon and unreacted monomer from the polymer before the carbonylation step of the Koch reaction, the amount of light ester impurities generated was minimized. Light ester is an undesirable byproduct that adversely affects the recycle of the catalyst from the functionalization step of the Koch reaction. The invention also pertains to improved lubricating oil nitrogen-containing dispersant additives derived from fractionated polymer.
