Abstract: This invention is directed to processes of making polymer in the presence of a hydrofluorocarbon or perfluorocarbon and recovering the polymer. The processes provided enable polymerization processes to be practiced with minimal fouling in the reaction system, and provide polymer products that can be manufactured to relatively low densities. The invention is particularly beneficial in the production of ethylene based polymers using chromium catalyst systems.

Abstract: This invention is directed to processes of making polymer in, the presence of a fluorinated hydrocarbon and recovering the polymer. The processes provided enable polymerization processes to be practiced with minimal fouling in the reaction system, and allows for the recovery of the fluorinated hydrocarbon and other hydrocarbons such as hydrocarbons for re-use in the process or hydrocarbon by-products from the polymerization process. The invention is particularly beneficial in the production of propylene-ethylene based copolymers using Ziegler-Natta catalyst systems.

Abstract: This invention is directed to a polymerization process that is carried out at relatively high productivity levels and with relatively low fouling. The process includes mixing together a catalyst system, at least one monomer and a hydrofluorocarbon to produce the polymer. The reaction is carried out such that little to no chlorine containing hydrocarbons are present.

Abstract: A method for maintaining the activity of silicoaluminophosphate (SAPO) molecular sieve catalyst particles during oxygenate to olefin conversion reactions. The SAPO catalyst particles are regenerated under targeted conditions in the presence of platinum to provide controlled, steady state regeneration while minimizing catalyst damage.
