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.

Abstract: The present invention aims to provide a method for improving the fluidity of a crystal nucleating agent for polyolefin resins without impairing other properties, and a polyolefin resin composition containing the crystal nucleating agent with improved fluidity and having excellent properties including transparency, and a molded article thereof. A crystal nucleating agent controlled to have specific characteristics can achieve improved fluidity, and the use of such a crystal nucleating agent having specific characteristics remarkably improves the workability during molding processing and provides a polyolefin resin composition excellent in properties such as transparency, and a molded article thereof.
