Abstract:
The adhesion between a low surface energy (i.e., nonpolar) material, e.g., a polyolefm such as polyethylene, and a high surface energy (i.e., polar) material, e.g., a polyester, polyurethane, polycarbonate or polylactic acid, is promoted by blending with the nonpolar material typically from 15 to less than 50 wt% of a diol-based thermoplastic polyurethane (d-TPU), e.g., a polydiene diol-based TPU, based on the combined weight of the nonpolar material and the d-TPU. The promoted adhesion allows for the effective painting, printing, over-molding or HF-welding of a nonpolar substrate, e.g., a polyolefin film, with a polar coating, e.g., a paint, ink, etc. Aqueous dispersions can also be made from the blend of nonpolar material and d-TPU.
Abstract:
The invention provides polyolefin blend compositions of polar and/or non-polar polymers, with at least one functionalized polyolefin polymer selected from the group consisting of: amine functionalized, hydroxyl functionalized, imide functionalized, anhydride functionalized, or carboxylic acid functionalized polyolefin polymers. The invention also provides methods for making the functionalized polyolefin polymer. The invention also provides for materials and articles containing at least one component prepared from such compositions.
Abstract:
The invention provides a composition comprising the following: at least one olefin multi-block interpolymer, at least one thermoplastic polyurethane, and at least one polydiene-based and/or polydiol-based polyurethane. These compositions are well-suited for promoting the adhesion between polar (for example, polyester, polycarbonate and polylactic acid) and non-polar materials and for the manufacture of, among other things, films, fibers, sheets and tie layers, tubes, adhesives, dispersions, protective apparel, footwear, coatings, laminates and foams.

Abstract:
El óxido de magnesio (MgO) formado en un compuesto en un polímero puede posteriormente ser hidratado en el sitio dentro del polímero para formar hidróxido de magnesio. En el caso de resinas que se pueden reticular basadas en silano o peróxido, la hidratación del MgO y la reticulación del polímero se pueden hacer en un solo paso del proceso, o en pasos consecutivos. En el caso de compuestos que no se pueden reticular, la hidratación se puede llevar a cabo después de formar el compuesto (sin paso de reticulación). En todos los casos, el vapor CV, el sauna, o baño de agua caliente son opciones para hidratación. Este método hace posible la preparación de los compuestos del polímero que son retardantes de flama con hidratos de metal todavía libres de la limitaciones tradicionales impuestas por la inestabilidad en el almacén, el quemado en la extrusión, la deshidratación no deseada, y las limitaciones de temperatura de procesamiento de los hidratos de metal.
