Abstract
The present invention relates to a halogen containing polymer compound containing a modified zeolite stabilizer. The modified zeolite stabilizer has a small particle diameter, narrow particle size distribution and less than 10 weight percent water. The modified zeolite stabilizer is formed by shock annealing, coating or a combination of the two methods.
