Abstract: Toughened thermoplastic compositions comprising a thermoplastic polymer toughened by the inclusion of a thermoplastic elastomer derived from a particulate rubber dynamically vulcanized in the presence of a matrix polymer. The toughened thermoplastic composition exhibits properties including toughness, improved impact resistance, and improved hardness. The compositions are utilized wherever toughened, high performance polymers are desired. A method for forming the toughened polymer compositions is also described. Processing methods, such as rotational molding, utilizing the toughened polymer compositions are described.

Abstract: The use of polytetrafluoroethylene micropowders having a particle size of generally less than about 20 microns as an additive for polyvinyl chloride or polyolefin unexpectedly produces compositions which are melt processable. Other unexpected properties include that the micropowder is deformable under shear and acts as a flame retardant.

Abstract: A polymer composition capable of depleting oxygen from adjacent spaces is disclosed. One or more botanical extracts, either naturally occurring or synthetic, that contain proanthocyanidin or its derivatives are added to a base polymer or polymer blend prior to processing to provide the polymer with oxygen-scavenging benefits without adverse effect to the characteristics of the base polymer or polymer blend.

Abstract: A method of making a multilayered, resilient flooring containing a multicolored pattern is disclosed. The method includes applying a multiplicity of pigmented, thermoplastic microbeads to a top surface of a thermoplastic base layer to form a pattern layer on the base layer, which typically remains sufficiently hot so that it is molten or tacky when the microbeads are applied. The base layer and pattern layer can be covered with a substantially transparent material to form a clear top layer. The base layer can be formed by melting a dry blend comprising polyvinylchloride (PVC) to produce a molten PVC output, shaping the molten PVC output into a smooth PVC sheet of uniform thickness. The microbeads can be applied to the base layer using a stencil. The multiplicity of microbeads can include microbeads of two or more colors. Preferably, the microbeads are approximately spherical and have an average diameter between 0.002″ and 0.040″.
