POLYMERIZATION PROCESS

摘要

This invention relates to a process to polymerize olefins comprising: contacting: (i) propylene and (ii) a mixture comprising, optionally ethylene, and three or more different alpha olefins having 4 to 20 carbon atoms, wherein at least one alpha olefin is present at Z percent or more, based upon the weight of the mixture, where Z = Y+ X, where X = (100 divided by the number of alpha olefins present in the mixture) and Y equals 1 to 75, where Z is not more than 95%, with (iii) a metallocene catalyst system.
