Abstract: Molecular sieves are prepared by forming a reaction mixture slurry, spray drying the reaction mixture slurry to form particles, and heating the spray dried reaction mixture at a temperature and pressure sufficient to cause crystallization of the molecular sieve. The reaction mixture contains an organic templating agent capable of forming the molecular sieve. The template may be added to the reaction mixture either by adding all of the template prior to spray drying, or by adding a portion of the template prior to spray drying with the remainder being added after spray drying.

Abstract: The present invention describes halogenated polymer resins stabilized with one or more co-stabilizers, at least one co-stabilizer comprising a synthetic crystalline aluminosilicate of the formula M2/nO.Al2O3.ySiO2.wH2O, in which M is a charge balancing cation, n is the valence of M and is 1 or 2, y is the number of moles of SiO2 per mole of Al2O3, and is 1.85 to 15 with a preferred range of about 2 to 5, and w is the moles of water of hydration per molecule of said aluminosilicate, wherein said aluminosilicate has a mean crystallite size in the range of about 0.01 &mgr;m to about 1 &mgr;m and a mean particle size in the range of about 0.1 to 10 &mgr;m. Also described is a method for stabilizing halogenated polymers such as PVC and CPVC by incorporating said aluminosilicate into a formulation thereof. A zeolite process improvement for creating a dehydrated zeolite that does not substantially rehydrate is also described.
