    摘要: Processes for polymerizing propylene. About 40 wt % to about 80 wt % propylene monomer, based on total weight of propylene monomer and diluent, and about 20 wt % to about 60 wt % diluent, based on total weight of propylene monomer and diluent, can be fed into a reactor. The propylene monomer can be polymerized in the presence of a metallocene catalyst and an activator within the reactor at a temperature of about 80° C. or more and a pressure of about 13 MPa or more to produce a polymer product in a homogenous system. About 20 wt % to about 76 wt % (preferably About 28 wt % to about 76 wt %) propylene monomer, based on total weight of the propylene monomer, diluent, and polymer product, can be present at the reactor exit at steady state conditions.
