Abstract
A spray-dryable composition is provided, comprising a catalyst compound, an activator for the catalyst compound, and at least one compound selected from among siloxanes, polyethylene glycols and crown ethers, the composition optionally further comprising a filler. There are further provided a method of spray-drying such a composition, and polymerization processes which employ such spray-dried compositions.
Claims11
A method of spray-drying a catalyst composition comprising atomizing a mixture comprising said catalyst composition, an inert liquid hydrocarbon medium, and at least one inert drying gas thereby creating a spray or dispersion of droplets comprising said catalyst composition, and evaporating the inert liquid hydrocarbon medium, said catalyst composition comprising a catalyst compound, an activator for said catalyst compound and at least one compound selected from the group consisting of siloxanes, polyethylene glycols and crown ethers.
A method of spray-drying a catalyst composition comprising atomizing a mixture comprising said catalyst composition, a liquid medium, and at least one inert drying gas thereby creating a spray or dispersion of droplets comprising said catalyst composition, and evaporating the liquid medium, said catalyst composition comprising a catalyst compound selected from the group consisting of:
- an activator for said catalyst compound and at least one compound selected from the group consisting of siloxanes, polyethylene glycols and crown ethers.
