摘要： 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.
