Abstract: Polyester resin compositions each comprising a polyester resin and a silane-treated phyllosilicate, wherein the silane-treated foliated phyllosilicate is one prepared by incorporating a swellable phyllosilicate salt with organo-silane of the general formula (I): YnSiX4−n (wherein n is an integer of 0 to 3; Y is an optionally substituted C1-C25 hydrocarbon group; and X is a hydrolyzable group or hydroxyl, with the proviso that when n or 4−n is 2 or above, nY's or (4−n)X's may be the same or different from each other) and the maximum layer thickness of the silane-treated foliated phyllosilicate in the composition is larger than 100 Å but smaller than 2000 Å.
Abstract: The invention relates to rubber blends containing said at least one solution-polymerized rubber containing hydroxyl groups, synthesized from diolefins and vinylaromatic monomers, wherein said at least one solution-polymerized rubber containing hydroxyl groups contain in the region of 0.1 to 5 wt. % of bonded hydroxyl groups, to a process for their preparation and to their use for the production of all kinds of moldings.

Abstract: Intercalated layered materials prepared by co-intercalation of a multi-charged onium ion spacing/coupling agent and a matrix polymer between the planar layers of a swellable layered material, such as a phyllosilicate, preferably a smectite clay. The spacing of adjacent layers of the layered materials is expanded at least about 3 Å, preferably at least about 5 Å, usually to about 15-20 Å, e.g., 18 Å with the di-charged onium ion spacing/coupling agent. The intercalation of the matrix polymer then increases the spacing between adjacent layers to at least about 15 Å, preferably to about 20 Å to about 30 Å.

Abstract: A fragrant thermoplastic snow product for creating winter scenes and pleasing aromatic affects is set forth. The fragrant thermoplastic snow product includes a thermoplastic snow, and a fragrance applied to the thermoplastic snow. A method of manufacturing fragrant thermoplastic snow is also set forth. The method comprises the following steps. First, a batch of thermoplastic snow is provided. Next, a fragrance is mixed with the batch of thermoplastic snow. Finally, the batch of thermoplastic snow is dried.
Abstract: A method is provided for forming a highly conductive metal-containing polymer fiber or sheet in which a polymer is immersed in a solution containing a metal precursor selected from organic or inorganic salts of copper, silver, aluminum, gold, iron and nickel. The metal precursor is then reduced by chemical, electrochemical, or thermal means such that conductive metal is incorporated into the polymer.
