SYSTEM AND PROCESS FOR PRODUCTION OF POLYETHYLENE AND POLYPROPYLENE |
摘要 |
A method for producing a polyethylene or polypropylene polymer, or co-polymer thereof, comprises contacting a monomer-containing medium with polymerization catalyst particles in at least one high shear mixing device to form a nanodispersion, wherein the particles have a mean diameter less than 1 micron. The monomer is selected from the group consisting of ethylene, propylene, and combinations thereof. The method further includes subjecting the nanodispersion to polymerization conditions comprising pressure in the range of about 203 kPa to about 6080 kPa (about 2 atm to about 60 atm) and temperature in the range of about 20°C to about 230°C, whereby at least a portion of the monomer is polymerized. A system for carrying out the method is also disclosed.
