    摘要: A process for manufacturing continuous polyester filament yarn for technical applications from a polymer over 90% of the chains of which are composed of ethylene terephthalate units, via a one-step spinning process, with the undrawn filaments having a crystallinity smaller than 16% and the yarn being wound at a rate larger than 6000 m/min. The yarn obtained in this fashion is particularly suitable for use as reinforcing material in rubber articles, notably as reinforcing material in pneumatic tires for cars. The polyester filament yarn can be used to make cords of uncommonly high dimensional stability and a unique combination of breaking tenacity, shrinkage, and breaking toughness.

    摘要: This patent describes an economical and environment-friendly process for the synthesis of anionic clays with carbonate and/or hydroxide anions as the charge-balancing interlayer species. It involves reacting a slurry comprising an aluminium source and a magnesium source, the aluminium source comprising two types of aluminium-containing compounds, preferably aluminium trihydrate and/or thermally treated calcined aluminium trihydrate. There is no necessity to wash or filter the product. It can be spray dried directly to form microspheres or can be extruded to form shaped bodies. The product can be combined with other ingredients in the manufacture of catalysts, absorbents, pharmaceuticals, cosmetics, detergents, and other commodity products.
