Abstract:
A window envelope that includes a window patch formed from a low gloss polymer film based upon a rubber-modified vinyl aromatic polymer or a blend of a rubber- modified vinyl aromatic polymer and a vinyl aromatic polymer. The film may be a monolayer film or an external layer of a multilayer film. The film optionally includes an inorganic coating applied to either surface of the film where the film is a monolayer film or to an outermost surface of the film where the film is an external layer of a multilayer film. When an inorganic coating is applied to a film surface, the film need not include a rubber- modified vinyl aromatic polymer and may be based solely upon a vinyl aromatic polymer.

Abstract:
Un sobre de ventanas que tiene una o más aberturas de ventanas, estando al menos una abertura de ventana cerrada o sellada por un parche para ventanas no opaco, polimérico o de plástico, comprendiendo el parche para ventanas una película polimérica orientada biaxialmente, legible por escáner óptico, teniendo la película un brillo a 45º que es inferior o igual a 50 y comprendiendo una composición de polímeros orgánicos seleccionada de una resina de polímero vinilaromático modificado con caucho y una mezcla de una resina de polímero vinilaromático con una resina de polímero vinilaromático modificado con caucho, teniendo la resina vinilaromática modificada con caucho un tamaño medio de partícula sin restricciones dentro de un intervalo de 0,1 micrómetro a 10 micrómetros, en donde el polímero vinilaromático modificado con caucho está presente en una cantidad suficiente para proporcionar la película con un contenido de caucho igual o superior a 2 por ciento en peso basado en el peso de la película y hasta 9 por ciento en peso basado en el peso de la película.
Abstract:
A synthetic leather is made by a impregnating a non-woven or woven textile with an aqueous polyurethane dispersion comprised of a nonionizable polyurethane and an external stabilizing surfactant. The impregnated textile is then exposed to water containing a coagulant for a coagulation time sufficient to coagulate the dispersion. The method may be used to form a synthetic leather having excellent wet ply adhesion and may contain an insoluble multivalent cation organic acid.
