    摘要: The present invention relates to polyurethane-urea elastomers with exceptional mechanical properties and enhanced elasticity based on molecular structure analysis. The present invention involves the synthesis of a polyurethane-urea elastomer using a combination of commercially available materials: (1) polyols with ultralow unsaturation and narrow polydispersity, (2) diisocyanates with symmetric steric conformation, and (3) bulky diamines between functional groups. The preparation method for the novel polyurethane-urea is disclosed. The subject elastomers have the highest reported elongation-at-break among known polyurethane elastomers.

    摘要: An olefin polymerization catalyst and preparation method and use thereof are provided. The components of the catalyst comprise an active magnesium halide, a titanium compound containing at least one Ti-halide bond loaded on the active magnesium halide, and an internal electron donor selected from one or more silicon esters compounds having formula (I). The method for preparing the catalyst components is that: adding spherical magnesium chloride alcoholate particles and the electron donor into the solution of titanium compound in sequence, and processing with the titanium compound for one or more times to obtain the catalyst. The catalyst system used for the olefin polymerization comprises the catalyst components, a cocatalyst and an external electron donor. The catalyst has high activity for the propylene polymerization, and the activity is 4399 gPP/gTi·h(50° C., 1 h, slurry polymerization at atmospheric pressure), and the isotacticity of the polymer is 98%.

    摘要: A system and method for managing mass compromise of financial transaction devices is disclosed. A method includes maintaining a summary of a transaction history for a financial transaction device, and forming a device history profile based on the transaction history, the device history profile including predictive variables indicative of fraud associated with the financial transaction device. A method further includes generating a fraud score based on the predictive variables, the fraud score representing a likelihood that the financial transaction device is compromised will be used fraudulently.
