A process for the preparation of a coated substrate is described, in which a substrate is coated with a coating mixture containing a polymer and an amino acid-modified layered double hydroxide. The process of the invention is markedly simpler than conventional techniques for affording coated substrates having reduced permeability to degradative gases. The coated substrates obtainable by the process are particularly useful in packaging applications, notably in the food industry.

Provided are resin composition and a molded article produced therefrom, the resin composition comprising: a polycarbonate resin; a rubber-modified aromatic vinyl-based copolymer resin; a conductive additive including a carbon fiber and a carbon nanotube; talc; and a foaming agent, wherein the carbon fiber and the carbon nanotube are contained in a weight ratio of 1:0.1 to 1:0.4.

Provided are a superabsorbent polymer and a preparation method thereof. According to the present invention, a superabsorbent polymer having high centrifuge retention capacity and absorption rate may be prepared by using a specific foam stabilizer.

The present invention relates to processes for making compatibilized high aspect ratio barrier additives and polymer compositions that comprise compatibilized high aspect ratio barrier additives. The invention also relates to compositions produced by these processes, and articles formed from polymer compositions of this invention. The barrier additives provide passive barriers to gas molecules such as oxygen and carbon dioxide minimizing transit of such molecules through sidewalls of polymer articles containing the barrier additives.

The present invention relates to polyurethane based solid surface materials with improved dimensional stability which can be made using conventional inorganic fillers without pre-treatment of the fillers.

A method for producing a thixotropic curable silicone composition is provided. The curable silicone composition comprises: (A) a silicone base material comprising: an organopolysiloxane having at least two alkoxysilyl-containing groups per molecule and a filler other than fumed silica; (B) a hydrophobic fumed silica; (C) a carbasilatrane derivative; (D) an alkoxysilane or its partial hydrolysis and condensation product; and (E) a condensation reaction catalyst. The method comprises the following steps: (I) mixing components (A) and (B); (II) mixing component (C) with a mixture obtained by step (I); and (III) mixing components (D) and (E) with a mixture obtained by step (II) under free of moisture. The curable silicone composition obtained by the method has an excellent thixotropic property and can cure at room temperature by contact with moisture in air.
