Patent number: 5744555Abstract: A process for the production of elastomeric polypropylene is disclosed. The process entails contacting the propylene monomer neat or in an unreactive hydrocarbon solvent, with a catalyst in a recirculated, stirred reactor at a temperature of about 60.degree. to 80.degree. C. thereby producing elastomeric polypropylene. The reactor contents are in the slurry/solution phase and are essentially free of catalyst poisons. The reactor is capable of recirculating contents that are very viscous such that the reactor contents are well mixed while a portion of the contents of the reactor containing propylene, any solvent, and elastomeric polypropylene are continually removed by the use of a high viscosity pump to recover the elastomeric polypropylene.Type: GrantFiled: November 25, 1994Date of Patent: April 28, 1998Assignee: Eastman Chemical CompanyInventors: William A. Ames, Robert E. Holliday, Timothy J. McKeon, Luis A. Pagan, James H. Scott, Horst K. Seeger, Gregory T. Slemons, Max Statman, Jeffrey J. Vanderbilt
