Abstract: Polymeric film structures incorporating at least one coating comprising a cross-linked EVOH copolymer and coating solutions suitable for use on polymeric films comprising at least one EVOH copolymer and at least one cross-linker are provided. The coated films may be single or multi-layered film structures. The films may also be metallized. The coated films exhibit beneficial water vapor and oxygen transmission rates. The coated films may also exhibit the beneficial barrier characteristics under conditions of high humidity. The coated films are suitable for packaging applications. The coating solutions exhibit beneficial stability characteristics over extended time periods.

Abstract: A process for producing a monoalkylation aromatic product, such as ethylbenzene and cumene, utilizing an alkylation reactor zone and a transalkylation zone in series or a combined alkylation and transkylation reactor zone.

Abstract: The invention relates to a process for producing alkylated aromatics, preferably ethylbenzene, in a multiple bed reactor in which at least two catalysts, each comprising a molecular sieve, are used in sequential beds. The first alkylation catalyst is selected to have a higher activity or alpha value than the subsequent alkylation catalyst.

Abstract: The invention relates to a process for producing a desired dialkylbenzene isomer having a formula R2C6H4, where R is an alkyl substituent, by contacting a polyalkylbenzene compound of formula RnC6H6-n, where n is an integer between 2 and 4, with a monoalkylbenzene compound of formula RC6H5 in the presence of a molecular sieve catalyst under reaction conditions sufficient to produce said dialkybenzene isomer. The preferred molecular sieve catalysts have pores or surface cavities greater than 5.6 Angstroms in diameter and/or an X-ray diffraction pattern including d-spacing maxima at 12.4±0.25, 6.9±0.15, 3.57±0.07, and 3.42±0.07 Angstrom.
