  • Halogen containing polymer compounds containing modified zeolite stabilizers
    Publication number: 20030166752
    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.
    Type: Application

  • Modified zeolites and methods of making thereof
    Patent number: 6180549
    Abstract: The present invention relates to zeolites and the process for forming such zeolites. In addition, the instant invention relates to modified zeolites having a reduced water content while retaining the reactivity toward the acid species. The reduction in the water content is achieved by shock annealing or coating. The modified zeolite is useful as a stabilizer for halogen containing polymers.
