Abstract: Provided is a method for preparing a polymer nano-composite, more particularly, an economical method for preparing a polymer nano-composite with improved properties via a single process of organic treatment of a layered clay mineral and dispersion in a rubber latex material at a pH where both the rubber latex material and the layered clay mineral are stabilized. The provided method for preparing a polymer nano-composite allows effective dispersion without using an organic modification process for improving dispersibility of the layered clay mineral in resin. Thus prepared polymer nano-composite exhibits superior mechanical property and may be usefully applied for automobile interior and exterior materials.

Abstract: The present invention provides a process for making silica-filled rubber masterbatch using silica hydrophobated with a trimethoxy silane coupling agent that is soluble in an alcohol-water solution containing at least about 70 wt % water. One embodiment uses a mixture of trimethoxy silanes, one or more of which react with rubber to bond the silica to the rubber, and one or more of which do not react with rubber, but do hydrophobate the silica. Hydrophobated silica is mixed with latex polymer and incorporated into rubber during coagulation of the latex, which is preferably coagulated with calcium chloride. The present invention further provides a process for making the trimethoxy silane coupling agents. Preferred trimethoxy silane coupling agents include bis-(3-trimethoxysilylpropyl)-disulfide and bis-(3-trimethoxysilylpropyl)-tetrasulfide. Rubber products, particularly tires, compounded with the inventive silica masterbatch can be processed for a long time before scorching because the silica masterbatch provides a long scorch time.

Abstract: The present invention is directed to the provision of premixed aqueous compositions which are used to provide a paint composition of varying finish characteristics at the point of sale. Thus, the merchant distributing the paint composition made from the subject premixed compositions need only maintain inventory of four compositions. The particular compositions which are the subject of the invention exhibit stable characteristics during storage in their respective reservoirs. The compositions include a pigment composition, a dispersant thickening agent, a high resin content binder, and a low resin content binder. The compositions are combined in differing amounts to produce paint compositions being suitable for either interior or exterior use and having differing sheens, quality levels, and color bases.
