Patent ID: 7354979

Claim:
A process to polymerize olefins comprising contacting, in a polymerization system, olefin monomers having three or more carbon atoms with: 1) a metallocene catalyst compound, 2) an activator, 3) optionally comonomer, and 4) optionally diluent or solvent, at a temperature above the cloud point temperature of the polymerization system and a pressure no lower than 10 MPa below the cloud point pressure of the polymerization system and less than 1000 MPa, where the polymerization system comprises the monomers, any comonomer present, any diluent or solvent present, and the polymer product, where the olefin monomers are present in the polymerization system at 40 weight % or more, and where polymerization takes place in a loop reactor operated at pressures of 25 to 30 MPa.
