Abstract: Disclosed are silica bound zeolite adsorbent particles which possess high volumetric gas adsorption capacity for the adsorption and/or desorption of gases. The adsorbent are highly effective as a gas source in volumetrically constrained applications. The silica-bound zeolite adsorbents possess a relatively high zeolite content simultaneously with a relatively low intra-particle pore volume as compared to the clay bound zeolite aggregates heretofore used as a gas source in volumetrically constrained environments, e.g. instant beverage carbonation processes, devices or systems.

Abstract: The present invention provides polymer compositions having improved corrosivity, color stability and clarity. Also disclosed is a process of preparing the polymers. The process may comprise incorporating into the polymer an acid neutralizing amount of an amorphous aluminum silicate. The amorphous aluminum silicate may be present in the polymer in an amount such that the polymer composition having a Corrosivity Index of less than 6. A refractive index of the amorphous aluminum silicate may be the same or substantially the same as a refractive index of the polymer.
